2017 vol 1 (1) i. the purpose behind catalog: oregon state arthropod collection is to provide a means by which the oregon state arthropod collection (osac) can record, disseminate and archive records, documents, datasets and information related to the collection, which are not often formally published/archived elsewhere. because of this, these resources can be hard to access and easily lost over time. anyone who has worked closely with natural history collections is aware that in addition to the specimens themselves, these institutions generate and maintain a host of other records, documents and information related to the specimens and the research activities associated with them. in some cases, these records hold useful biological information related to specimen label data; in other cases they provide historical context about how specimens arrived (or left) the collection. these types of records are seldom published in any real sense and exist often as single copy files in file cabinets or sometime recorded in abbreviated formats in hand-written catalogs or as database entries. the development of archived digital-only journals provides a flexible low cost option for storing these types of documents. use of a journal format allows end users, data producers and archivists a long established mechanism for consolidating these records while making them vastly more available to the research community. in addition to increasing availability, a museum focused journal takes advantage of several established academic traditions: (1) journals provide a stable long-term and indexed structure for recording the information, (2) journals (electronic and printed) are known quantities for librarians and archivists, and thus the museum community need not re-invent standards for sharing and archiving this information and (3) it allows researchers making use of the information in scholarly works, an easy method of citing the information source. it is hoped that by making these records ‘citable’ in the standard sense, the important role that museums/natural history collections play in providing foundational data for research papers may become more visible via their inclusion in bibliographies of those papers. christopher j. marshall catalog: oregon state arthropod collection 2019 vol 3 (2) catalog: oregon state arthropod collection transactions loan

http://dx.doi.org/10.5399/osu/cat_osac.3.2.4590 introduction these records were generated using funds from the lepnet project (seltmann et. al., 2017) a national collaborative effort to create digital records for north american lepidoptera. the dataset published herein contains the label data for all north american specimens of hepialidae residing at the oregon state arthropod collection as of march 2019. a beta version of these data records will be made available on the osac server (http://osac.oregonstate.edu/ipt) at the time of this publication. the beta version, entitled, osac_heplialidae_2019_ver_beta will be replaced in the near future with an official release (osac_hepialidae_2019_ver_1.0), which will then also be archived as a supplemental file to this publication. methods basic digitization protocols and metadata standards can be found in (shepard et al. 2018). identifications were made by jon shepard with reference to an unpublished key to the pnw hepialidae wagner (1983). identification and nomenclature were checked against the digital guide to moth identification (moths protographers group, 2019). results as of march 2019, the collection possessed 70 specimens of north american hepialidae, belonging to the genera: sthenopis pagenstecher, 1909, phymatopus wallengren, 1869 and gazoryctra hübner, 1820 (table 1) additional material from outside of north america is also present in the holdings, but was not digitized and catalogued at this time. label data for these specimens can be accessed via online data portals that digest osac ipt data directly (e.g, www.gbif.org) or by accessing the archived datasets stored in the supplemental files of this paper. catalog: oregon state arthropod collection 2019 vol 3 (2) taxon # specimens sthenopis

the normal business hours of oregon state university. numerous non-research visits are also scheduled throughout the year. the collection strives to record this usage of the collection in our visitor log, a physical sign-in book located near the entrance of the collection. the table below records those entries for the 2018 calendar year, although a few illegible entries were necessarily omitted. a scanned pdf of the pages themselves may be added at a later date and if so, will be added as a ‘supplemental file’ to this publication. visitors wishing to cite their visit to the collection in scholarly work may do so using the following citation: oregon state arthropod collection. 2019. visitor log. january-december, 2018. catalog: oregon state arthropod collection 3(1). pp 7–9.

university, corvallis or 97331 vol 1(1), 1-3 abstract: a dataset of 260 skipperling specimens belonging to the genus oarisma is presented along with information pertaining to how the label data was digitized and the metadata standards adopted. a brief synopsis of the dataset is provided along with a supplemental .csv file containing the data records themselves. in 2016, as part of lepnet (seltmann et. al., 2017) a national effort to create digital records for north american lepidoptera the oregon state arthropod collection began digitizing label data associated with its butterfly and moth collection. while most of the hesperiidae has not yet been digitally captured a concerted effort was launched across the lepnet participants to see if we could rapidly generate a dataset for oarisma with the aim of assisting conservation efforts for oarisma poweshiek (parker, 1870; fig 1) being led by dr. anna monfils at central michigan university. the dataset published herein contains the label data for all specimens residing at the oregon state arthropod collection as of august 2017. introduction cite this work, including the attached dataset, as: shepard, j. h, c. j. marshall. 2017. specimen records of oarisma scudder 1872 (lepidoptera: hesperiidae) in the oregon state arthropod collection, osu, corvallis, or.. catalog: oregon state arthropod collection 1(1) p.1-3. http://doi.org/10.5399/osu/cat_osac.1.1.3995 methods all specimens are given unique serial number (catalog number) that are printed using a machinereadable barcodes as well as a human readable numerals on an acid-free card-stock labels that are placed as the bottom-most label. data standards: all label data is consistent with darwincore standards for occurrence data (http:// rs.tdwg.org/dwc/terms/occurrence). taxonomic treatment: the taxonomic identity for all specimens was re-confirmed prior to digitization. to ensure nomenclatural validity, all names were checked and standardized according to pelham (2008). locality and georeference data. locality data was transcribed into the dublincore location fields (http://purl.org/dc/terms/location). namely: country, stateprovince, county and locality. missing information (e.g., no county printed on actual specimen label) was added to a record if it could be determined without ambiguity based on gazetteers, maps or in reference to other label data. elevational data on labels were converted to minimumdistanceabovesurfaceinmeters. elevational ranges (e.g, 500-1200m) were recorded as the lower of the two. when available, decimallatitude and decimallongitude were included, but not all records were georeferenced at this time. 1 http://doi.org/10.5399/osu/cat_osac.1.1.3995 http://rs.tdwg.org/dwc/terms/occurrence http://rs.tdwg.org/dwc/terms/occurrence http://purl.org/dc/terms/location results acknowledgements metadata: basisofrecord for each occurrence was entered as preservedspecimen with the collector(s) listed on the label stored in the recordedby field. the occurrenceid is a uri for the specimen record itself, and includes the catalog number: “http://osac.oregonstate.edu/sp/osac_xxxxxxxxxx” where “xxxxxxxxxx” is the 10-digit unique catalog number for the specimen. two hundred and sixty specimens identified as oarisma were located, belonging to three species: o. poweshiek (parker, 1870), o. garita (reakirt, 1866), o. edwardsii (barnes, 1897). not surprisingly, the majority of specimens belonged to o. garita which occurs throughout the pacific northwest (guppy & shepard, 2001). fourteen records for the endangered species, o. poweshiek were found (fig 1.) from two localities, one in michigan and one in iowa, all from the 1970’s and 1980’s. discussion references with only two localities and 14 specimens the osac’s holdings may seem meager in the face of understanding present day distributional information for the endangered o. poweshiek. perhaps the distributional records for its pnw congener, o. garita, for which the osac has much better coverage, may provide useful clues in the distribution of its eastern relative. it is hoped, that once these records are combined with those of other institutions, the larger dataset might provide more insights still. guppy, c. s. & j. h. shepard. 2001. butterflies of

(2015). locality and georeference data. locality data was transcribed into the dublincore location fields (http://purl.org/dc/terms/location); namely: country, stateprovince, county and locality. missing information (e.g., no county printed on actual specimen label) was added to a record only if it could be determined without ambiguity based on gazetteers, maps or in reference to other label data. elevational data on labels were converted to minimumelevationinmeters. elevational ranges (e.g, 500-1200m) were recorded as the lower of the two. georeferencing for locality data was conducted by searching googleearth for the most appropriate placenames and recording the decimal degree latitude and longitude associated with that point. because of the ambiguity in this approach it is recorded at a tenth of a degree metadata: record type is considered physicalobject and basisofrecord is entered as preservedspecimen. the collector(s) of the specimen are entered in the recordedby field. the occurrenceid is a uri for the specimen record itself, and includes the catalog number: “http://osac.oregonstate.edu/sp/osac_xxxxxxxxxx” where “xxxxxxxxxx” is the 10-digit unique catalog number for the specimen. results one hundred and eight specimens of alpinobombus were found in the holdings of the osac, belonging to 6 species, with 4 of the 6 north american species being represented (table 1). nineteen specimens were not identified to species level. label data for 20 specimens were not included in the supplemental dataset, as their labels lacked appropriate locality information or could not be interpreted reliably at this time. discussion these data are presented for use by researchers and conservationists interested in bombus (alpinobombus) historical records. they are available for use either via download from the supplemental file associated with this publication (.csv text format) or will be shared online via an ipt server, accessible through gbif (www.gbif.org). access via gbif is recommended, as that dataset will include the most recent version of these records in the case that they are modified/updated at a later date. use of any of these records, in print or in online datasets and websites, should cite the dataset appropriately. comments, edits or corrections to particular data records should be sent to osac@science.oregonstate.edu or

were generated using funds from the lepnet project (seltmann et. al., 2017) a national effort to create digital records for north american lepidoptera. the dataset published herein contains the label data for all north american specimens of cossidae and sesiidae residing at the oregon state arthropod collection as of march 2019. a beta version of these data records will be made available on the osac server (http://osac.oregonstate.edu/ipt) at the time of this publication. the beta version will be replaced in the near future with an official release (version 1.0), which will be archived as a supplemental file to this paper. methods basic digitization protocols and metadata standards can be found in (shepard et al. 2018). much of the newer material was identified by two specilaists on sesiidae: mr. john vernon and mr. benjamin g. thompson. identifications were reviewed by jon shepard and paul hammond using barnes and mcdunnough (1911) and the digital guide to moth identification (moths protographers group, 2019). nomenclature follows that of hodges (1983) and the moth photographers group (2019) and was checked again using the species matching tool produced by gbif (https://www.gbif.org/tools/ species-lookup). results as of march 2019, the collection possessed 181 specimens of north american cossidae, belonging to 8 known species classified into 6 genera:

data for these specimens can be accessed via online data portals that serve osac ipt data (e.g., www.gbif.org) or by direct download via the archived datasets stored in the supplemental files of this paper. catalog: oregon state arthropod collection 2019 vol 3(2) discussion: in the pacific northwest, cossidae are most common and diverse east of the cascade mountains in association with their larval food plants that include aspen and willow in riparian habitats. however, one california species, toronia perplexa, can be found uncommonly in coniferous forests along the west slope of the cascade range. currently the osac’s holdings of t. perplexa amount to but 5 specimens, 4 of which were taken at the h. j. andrews experimental forest near blue river, oregon. more surveys of the western cascades during their flight season could significantly expand the known range of this species in oregon. osac’s holdings of north american sesiidae are more comprehensive, including nearly 60% of the currently known north american fauna (moths photographers group 2019; hodges 1983). this is largely the result of material placed into the collection by benjamin garrison thompson, who wrote his dissertation at oregon state agricultural college on clearwing moths (thompson 1929) as well as mr. john vernon, an outstanding sesiid enthusiast who gave his collection to the university in 2008. minor corrections and other small modifications made in the future to this dataset will be accomplished by issuing a new version and providing a file of modified records to the supplemental files. major additions, such as new records, new data fields, new contributors or other significant modifications will be accomplished through the generation and release of new datasets.

state arthropod collection. catalog: oregon state arthropod collection. 3(3) p 2–6 doi: http://dx.doi.org/10.5399/osu/cat_osac.3.3.4614 abstract a new oregon record for peponapis pruinosa (say, 1837) is presented with notes on its occurrence and photographs. this record provides the first empirical evidence of the genus and species in the state of oregon. a dataset of peponapis (say, 1837) specimens in the holdings of the oregon state arthropod collection is included with a brief summary of its contents. introduction bees of the genus peponapis (say, 1837) (apidae: eucerini) are known pollen-collecting specialists of cucurbita linnaeus, a genus of plants containing native species occurring in central america, mexico and the southwestern united states of america (hurd and linsley 1964; hurd et al. 1971). domesticated cucurbita species, including pumpkins, summer and fall squashes, marrows, and many other varieties, are widespread throughout north america, and have allowed members of the genus to expand their geographic range (lópez-uribe et al. 2016) accounts of individual bees visiting other flowers exist (e.g., ipomea), but the bees were not seen to collect pollen (mathewson 1968). in recent years, perhaps as an offshoot to honey bee decline, the visibility and importance of honeybees as well as native pollinators has grown both within the scientific community as well as the public at large (allchin 2018). much of the justification for this interest centers on the ecological and agricultural services provided by bees and other pollinators, however biological conservation of these species for their own sake is also championed (kleijn et al. 2015; matias et al. 2017). no matter the underlying justification, a key challenge to assessing pollinator health is a disconnect between a small and highly specialized community of bee taxonomists and the broader community who wish to know more about their local pollinators. unlike wild plants, birds or even a few large and showy insects (e.g., butterflies and dragonflies), many bee groups lack available and comprehensive diagnostic tools to identify genera and species, or the existing tools require extensive knowledge of bee anatomy and terminology. this is particularly true of the pacific northwest (pnw) region of north america where the native bee fauna has received comparatively less study than other parts of the us and canada. the oregon bee project is a multi-institutional partnership to develop and expand taxonomic knowledge of catalog: oregon state arthropod collection vol 3(3) 2–6 3 pnw bees through formal programs training citizen scientists to survey, identify and voucher the bees of our region. this paper represents the type of discovery that can be made when trained and interested members of the public (citizen scientists) have the capacity to work with professional scientists and compare their observations to historical records reported in scientific literature and stored in scientific research collections. new state record the oregon populations of peponapis were first noted by sarah red-laird (srl) in 2016 when a young participant in a bee biology camp she was leading noted a ‘flat honeybee’ in a squash flower. recognizing that the bee was unusual (e.g., not a honeybee), srl, took some photos and a specimen and later used online guides (www.bugguide.net) to determined that the bee was peponapis pruinosa. given that the bees were abundant on the organic farm where the camp took place, and that the p. pruinosa is widely distributed in north america, srl did not realize the species had not yet been confirmed to occur in oregon. two years later, at a bee taxonomy workshop (oregon bee school) led by lincoln r. best (lrb) species were discussed that were potentially in the state, but that had not yet been confirmed. at that time the importance of these earlier observations was recognized. new material (collected in 2018) was sent to corvallis to confirm the identification and deposit a voucher in the osac (figure 1). figure 1. voucher specimen of oregon peponapis pruinosa. osac_0001072794 efforts were then made to find other oregon historical records of peponapis in the osac, other collections, literature and online data portals (global biodiversity information facility gbif, inaturalist, bugguide, etc). no other confirmed records could be found at this time. catalog: oregon state arthropod collection vol 3(3) 2–6 4 three mis-transcribed specimen records originally three putative older records, from 1933, were retrieved from gbif based on specimens housed at the snow entomological collection (kansas university; catalog #’s 442547–442549) (thomas 2019). the digitized records indicate the specimens were all collected in late july from andover, oregon by an unknown collector and georeferenced as 45.33139 -122.2278, coordinates that correspond to eagle creek, oregon. there is no andover, oregon reported in the us geological society gazetteer (https://geonames.usgs.gov; (mcarthur and mcarthur 2003). a search for other bee specimen records from andover and the years around 1933 yield additional ku specimens, with photographed labels reading “andover, o” (figure 2), a label that should correctly be geo-referenced in ohio. zach fallin, collection manager for ku confirmed the peponapis labels match these others (personal communication), and are therefore also from ohio; and while they do not bear a collector’s name it also seems reasonable to assume they were likewise collected by the then 20 year old harold rodney dodge, who grew up in the vicinity of columbus ohio and would later become a professional entomologist specializing on diptera (telford and james 1973). the records have been updated, but we are reporting the update herein in case the online records were included in other derivative datasets/publications. additional peponapis records in addition to these two oregon records, we provide the label data for all the material currently housed at the osac. all specimens were determined (or redetermined) by lincoln r. best using keys produced by ayala and griswold (2012). there are 26 specimens from 4 species in the collection. the collection has 2 of the 6 known species that occur in the us (p. pruinosa and p. timberlaki), in addition to a mexican species (p. smithi) and the south american species: p. fervens (table 1). table 1. summary of digitized peponapis specimens species geographic origin of osac material p. pruinosa california, nevada, pennsylvania, oregon p. timberlaki arizona p. fervens argentina p. smithi mexico digitization methods each recorded specimen is affixed with unique identifier that is printed both as a machine-readable data matrix barcode and a human readable numeral. these identifiers are printed with archival ink on acid free cardstock and place on the specimen pin. label data was transcribed into observational figure 2. historical specimen labels from ku bee specimens from andover, o. catalog: oregon state arthropod collection vol 2(1) 2–6 5 specimen records and the data and metadata fields follow darwincore standards. the records were placed in an asci txt file (csv format) available for download as a supplemental file to this paper. additionally, the dataset has been shared via an ipt installed on the osac server: http://osac.oregonstate.edu/ipt), making the individual records retrievable via the gbif data portal: http://www.gbif.org. discussion any novel observational record for a species has the potential to contribute meaningful biodiversity information about the species’ geographic and temporal existence. in this case we report an observation for a particular species that had yet to be confirmed present in the state of oregon. although the absence or presence of a species within an artificial region such as a state or county has questionable biological importance, it has great social significance for tracking and communicating about biodiversity. humans navigate their relative position so heavily based on these units that to convert biological distributions into sociopolitical units not only makes it easier to communicate about biodiversity but it facilitates resources (funding, labor, legislation, etc) that are commonly allocated via these same geopolitically units. in fact, this novel record was produced by just such an endeavor, the oregon bee project, a citizenscience based collaboration that seeks to raise awareness and knowledge specifically about the bees of oregon. in this case, the synergy between professional scientists and non-professional entomologists is clear: the core observation was made by an interested and knowledgeable member of the public (s. red-laird), while the significance of that observation in terms of the overall oregon bee-fauna and the historical records for the region were added by a professional scientist (lincoln best) and scientific institutions (oregon state arthropod collection). knowing for certain that peponapis occurs in the state should also encourage others to seek it out and expand on the known distribution, which at the time of this publication is limited to ashland oregon. maintaining public interest and encouraging continued investment in citizen science programs can be challenging and a key are the non-monetary rewards of contributing to a worthwhile endeavor. in science, an important end product is ‘scientific discovery’: the realization of some truth or fact about the natural world that was previously unknown. by sharing the significance of an observation, or set of observations, with the individuals involved in generating them a citizen-science project re-invests in itself by sharing in the sense of discovery. in addition to discovery, science records its discoveries via publications (such as this) and including the individuals who contributed to those publications as co-authors or contributors is important so as to ensure that their real contributions towards making the scientific discoveries possible are not taken for granted or erased, which over time will underrepresent the challenges and man-power necessary to make large scale biodiversity discoveries possible. acknowledgments supported by the foundation for food and agriculture research under award number: 549024. the content of

respond to anthropogenic land use is key to conservation of biodiversity and ecosystem services, but few studies have addressed this topic in coniferous forests, particularly those managed intensively for wood production. this study reports on voucher material generated as part of zitomer et al. (2023), that assessed changes in wild bee communities with time since harvest in 60 intensively managed douglas-fir (pseudotsuga menziesii) stands in the oregon coast range across a gradient in stand age spanning a typical harvest rotation (0-37 years post-harvest). we additionally assessed relationships of bee diversity and community composition to relevant habitat features, including availability of floral resources and nest sites, understory vegetation characteristics, and composition of the surrounding landscape. specimens were collected using a combination of passive sampling methods-blue vane traps and white, blue, and yellow bowl trapsand hand-netting and were identified to the lowest possible taxonomic level by a.r. moldenke and l.r. best. four hundred and ten taxonomic voucher specimens were deposited into the oregon state arthropod collection (accession# osac_ac_2023_01_09-001-01) to serve as a reference for future research. catalog: oregon state arthropod collection 2019 vol 3 (2) specimen records for north american lepidoptera (insecta) in the oregon state arthropod collection. zygaenoidea: zygaenidae, latreille 1809, limacodidae, moore 1879, dalceridae dyar, 1898 and megalopygidae herrich-schäffer, 1855 jon h. shepard paul c. hammond christopher j. marshall oregon state arthropod collection, department of integrative biology, oregon state university, corvallis or 97331 cite this work, including the attached dataset, as: shepard, j. h., p. c. hammond, c. j. marshall. 2019. specimen records for north american lepidoptera (insecta) in the oregon state arthropod collection. zygaenoidea: zygaenidae, latreille 1809, limacodidae, moore 1879, dalceridae dyar, 1898 and megalopygidae herrich-schäffer, 1855. catalog: oregon state arthropod collection 3(2) (beta version). http://dx.doi.org/10.5399/osu/cat_osac.3.2.4593 introduction these records were generated using funds from the lepnet project (seltmann et. al., 2017) a national effort to create digital records for north american lepidoptera. the dataset published herein contains the label data for all north american specimens of zygaenidae, limacodidae, dalceridae and megalopygidae residing at the oregon state arthropod collection as of march 2019. a beta version of these data records will be made available on the osac server (http://osac.oregonstate.edu/ipt) at the time of this publication. the beta version will be replaced in the near future with an official release (version 1.0), which will be archived as a supplemental file to this paper. methods basic digitization protocols and metadata standards can be found in (shepard et al. 2018). identifications were confirmed prior to determination by jon shepard and paul hammond using the online digital guide to moth identification website (moth photographers group, 2019). nomenclature was confirmed using the species matching tool provided by gbif (https://www.gbif.org/tools/species-lookup). results the collection has only 232 specimens of north american zygaenoidea, the vast majority of which (204) belong to the family limacodidae. the genera present are: dalceridae: dalcerides neumoegen and dyar, 1893;

related to a dataset of observational records based on lepidoptera specimens in the oregon state arthropod collection (osac) (see: attached supplemental file). the dataset was generated as part of a nationally coordinated effort across entomological collections to build a shared data repository of north american lepidoptera records for use by scientists, conservationists and the public (seltmann et al. 2017). this contribution represents the second dataset to be shared by the osac. it includes label data records for 40,007 north american specimens belonging to the families: hesperiidae, papilionidae and pieridae. future published datasets will add additional records, including other taxa and specimens from other geographic regions. additionally, later releases may enhance, edit or modify pre-existing records when corrections, refinements and/or improved content (e.g., new taxonomic determinations or georeferencing, etc) as it becomes available. these new records will be archived in association with this publication and shared via an ipt server. housed at oregon state university: http://osac.oregonstate.edu/ipt/ methods prior to digitization, each specimen is provisioned with a unique serial number (catalog number) that is printed using a machine-readable barcode as well as a human readable numeral on an acid-free card-stock label that is catalog: oregon state arthropod collection vol 2(2) 1–2 2 typically placed, face down, as the bottom label for each specimen. data was then collected into fields consistent with darwincore standards for occurrence data (http://rs.tdwg.org/dwc/terms/occurrence). taxonomic treatment: the taxonomic identity for every specimen was confirmed by j. h. shepard prior to being captured. to ensure nomenclatural validity, all names were checked and standardized according to the pelham checklist (pelham 2008). locality and georeference data. label data were transcribed into the darwincore location fields (http://purl.org/ dc/terms/location). namely: continent, country, stateprovince, county and locality. missing information (e.g., missing county information for a given site) was added to a record if it could be determined without ambiguity based on gazetteers, maps or in reference to other label data. elevational data on labels were converted to minimumdistanceabovesurfaceinmeters. elevational ranges (e.g., 500-1200m) were recorded as the lower of the two. when available, decimallatitude and decimallongitude were included, but not all records were georeferenced at this time. metadata: basisofrecord for each occurrence was entered as preservedspecimen with the collector(s) listed on the label stored in the recordedby field. the occurrenceid is a uri that includes the catalog number: “http:// osac.oregonstate.edu/sp/osac_xxxxxxxxxx” where “xxxxxxxxxx” is the 10-digit unique catalog number for the specimen. supplemental file: the entire dataset is provided here as a supplemental file in a standard text file (comma separated values format). references: pelham jp (2008) a catalogue of the butterflies of the united states and canada. journal of research on the lepidoptera 40:

introduction these records were generated using funds from the lepnet project (seltmann et al. 2017) a national effort to create digital records for north american lepidoptera. the dataset published herein contains the label data for all north american specimens of crambidae in the collection as of march 2019. this dataset is not complete, as portions of our north american pyralidae remain to be digitized. this will be accomplished with a future dataset. a beta version of these data records will be made available on the osac server (http://osac.oregonstate.edu/ipt) at the time of this publication. the beta version will be replaced in the near future with an official release (version 1.0), which will be archived as a supplemental file to this paper. methods basic digitization protocols and metadata standards can be found in (shepard et al. 2018). identifications for this family are tricky, especially in the pacific northwest where the pyraloid fauna remains relatively unstudied. as a result, providing determinations to species, or even genus, was not always possible. in the interest of making these specimens visible to taxonomists, we include even those specimens identified only to family. generic and species determinations were reviewed prior to digitization by jon shepard and paul hammond using (group 2019). nomenclature follows that of the digital guide to moth identification (group 2019). results crambidae: there are 3461 specimens identified at species-level (species or subspecies), with another 123 specimens identifiable only to genus. the following

photovoltaic solar energy installation is booming, frequently near agricultural lands. traditionally, the land underneath ground-mounted photovoltaic panels is unused, though some are repurposing it as habitat for pollinating insects. however, the impact of the solar panel canopy on the pollinator-plant community understory is unknown. in this study (graham et al., 2020), we investigated the effects of solar arrays on plant composition, bloom timing and foraging behavior of pollinators in open fields (control), and in full shade and partial shade areas under solar panels in a predominant agricultural region of southern oregon. pollinating insect specimens were collected using hand nets, and identified to the lowest taxonomic group possible by m. graham, a.r. moldenke, and l.r. best. a total of 85 voucher specimens were deposited into the oregon state arthropod collection; accession record: osac_ac_2021_03_11_001-01. description of collection during the summer of 2019, we inventoried pollinating insects at the eagle point solar plant, a commercial solar facility in jackson county, oregon, as part of a study on plant-pollinator interactions in agrivoltaic systems (graham et al., 2020). in total, we sampled 458 insects using hand nets. surveys lasted 30 minutes, spanned a 100m² area, and were repeated eight times from may to september at approximately 2 week intervals. sampling occurred between 9 am and 4 pm, on warm (>16°c), calm (<20 km/h wind) days. surveys occurred at 3 distinct locations (blocks) throughout the solar facility. each block was partitioned into three treatment areas, one fully shaded (5% full sun) by the solar panels, one partially shaded (75% full sun), and one located in full sun (control). because of a maintenance issue, blocks a, b, and c were used during the first week of the survey, and blocks b, c, and d were used during weeks 2—8 of the survey. only records from weeks 2-8 of the survey were used for statistical analysis (graham et al. 2021). full sun and partial sun plots were surveyed when plots were unshaded. unshaded surveys were not possible in full shade plots, which were surveyed when shaded. we collected all insects observed touching the reproductive parts of flowers, excluding individuals from the family miridae, which were found in large quantities on stems, leaves, and flowers of some plants. after netting, we placed insects in ethyl acetate jars and froze for later identification. catalog: oregon state arthropod collection vol 5(2) 1—2 2 we pinned, sexed, and identified bee specimens to genus using keys produced for the campolin bee course (2012) and michener et al., 2007. when possible, we determined species-level identifications for bombus using: williams et al. 2008 and williams et al., 2014, and for halictus using: roberts, 1973. other pollinating insects were sorted to order or family where possible. ladybugs (coccinella and hippocampus) and leaf beetles (diabrotica) were identified to species with the website (www.discoverlife.org). these identifications were confirmed, and additional identifications made, by l.r. best and/or a.r. moldenke and checked with voucher specimens at the oregon state arthropod collection, department of integrative biology, oregon state university, corvallis, or. taxonomic names were confirmed with the gbif name matcher (https://www.gbif.org/tools/species-lookup). we collected a total of 458 insect specimens, representing five orders and 65 species of insects. the observation records for these specimens were made public via an ipt and can be accessed at www. gbif.org, and a copy of those records is archived as a text file (csv) attached to this publication. one voucher specimen was selected for each sex of each species collected, amounting to total of 85 voucher specimens, which were deposited into the oregon state arthropod collection; accession record: osac_ac_2021_03_11_001-01. acknowledgements

key to conservation of biodiversity and ecosystem services, but few studies have addressed this topic in coniferous forests, particularly those managed intensively for wood production. this study reports on voucher material generated as part of zitomer et al. (2023), that assessed changes in wild bee communities with time since harvest in 60 intensively managed douglas-fir (pseudotsuga menziesii) stands in the oregon coast range across a gradient in stand age spanning a typical harvest rotation (0-37 years post-harvest). we additionally assessed relationships of bee diversity and community composition to relevant habitat features, including availability of floral resources and nest sites, understory vegetation characteristics, and composition of the surrounding landscape. specimens were collected using a combination of passive sampling methods-blue vane traps and white, blue, and yellow bowl trapsand hand-netting and were identified to the lowest possible taxonomic level by a.r. moldenke and l.r. best. four hundred and ten taxonomic voucher specimens were deposited into the oregon state arthropod collection (accession# osac_ac_2023_01_09-001-01) to serve as a reference for future research. catalog: oregon state arthropod collection 2019 vol 3(2) specimen records for north american lepidoptera (insecta) in the oregon state arthropod collection. lycaenidae leach, 1815 and riodinidae grote, 1895 jon h. shepard paul c. hammond christopher j. marshall oregon state arthropod collection, department of integrative biology, oregon state university, corvallis or 97331 cite this work, including the attached dataset, as: shepard, j. s, p. c. hammond, c. j. marshall. 2019. specimen records for north american lepidoptera (insecta) in the oregon state arthropod collection. lycaenidae leach, 1815 and riodinidae grote, 1895. catalog: oregon state arthropod collection 3(2).

label data for these specimens can be accessed via online data portals that serve osac ipt data (e.g., www.gbif.org) or by direct download via the archived datasets stored in the supplemental files of this paper. discussion: today the oregon state arthropod collection maintains a relatively comprehensive representation of north american lycaenidae, built up over many decades through the contributions of at least 20 private collectors. a total of 156 species of lycaenidae have been recorded from north america and hawaii north of mexico as reported in pelham (2008) catalogue. of these, 149 (96%) are represented in the collection at the time of this writing, although 16 of these are represented by specimens from outside of this geographic range (e.g. further to the south) and were not included in this dataset. the majority of specimens is made up of taxa that occur in the pacific northwest and california, with generally good geographic coverage within these regions. in numerous cases (table 1) subspecies were not always formally recognized in the database given uncertainties as to their validity and/ or diagnosability. for example, while euphilotes columbiae and euphilotes ancilla are treated as valid species in pelham (2008) there is some disagreement among lepidopterists as to their proper rank (e.g,, the are often treated as subspecies of euphilotes enoptes) and not all lepidopterists consider them valid. the osac does possess determined material corresponding to all of these nominative taxa, but at the time of this publication we opted to treat them as euphilotes enoptes undetermined sspp. until we have more time to carefully review the taxonomy in greater detail. minor corrections and other small modifications made in the future to this dataset will be accomplished by issuing a new version and providing a file of modified records to the supplemental files. major additions, such as new records, new data fields, new contributors or other significant modifications will be accomplished through the generation and release of new datasets. acknowledgments the records published herein were generated with funds from nsf: dbi#1601888:

http://dx.doi.org/10.5399/osu/cat_osac.6.2.4962. abstract a private collection of 905 vials containing mostly aquatic macroinvertebrates is presented from dr. norman herbert anderson, professor of entomology at oregon state university from 1962-1995. the majority of these specimens were collected from multiple freshwater streams during his research at mount st. helens (wa, usa) soon after the may 18, 1980 eruption. this collection also includes 15 vials containing specimens collected by luis a. fusté from the muddy river (wa, usa) on march 29, 1980, less than 2 months before the eruption. the vast majority of these vials include a label indicating the sampling location, the date collected, and taxonomic identification. introduction this publication describes aquatic macroinvertebrate samples collected by dr. norman h. anderson between the years of 1980 and 1990. the majority of these specimens were collected from freshwater streams in the area surrounding mount st. helens (lawetlat’la in cowlitz) after the major eruption in 1980. the eruption caused many streams within the volcanic eruption zone to fill with ash, sediment, and woody debris from the surrounding forest. most samples with a known location were collected from ape creek, clearwater creek, or elk creek with a small minority originating from lakes surrounding mount st. helens. clearwater creek is located to the east of mount st. helens whereas elk creek is located directly to the west, offering some insight into how stream macroinvertebrates in different areas of mount st. helens were affected in the aftermath of the eruption. the samples were taken from two months prior to the eruption to up to a decade afterwards. historic collections like the ones described here make valuable comparisons to contemporary collections and surveys at mount st. helens. for example, surveys in 2016 of twenty-one locations across five new watersheds that have formed on the pumice plain, which experienced the most extreme level of disturbance during the 1980 eruption, resulted in collections of over 82 benthic macroinvertebrate taxa, including 74 aquatic insect taxa (claeson et al. 2021). primary succession research in stream ecosystems is limited, and assessments of genetic variation for early-establishing taxa may provide valuable information for understanding population dynamics in this ecosystem, as well as patterns of community assembly. catalog: oregon state arthropod collection vol 6(2) 2 methods approximately half of the vials in this collection are stored in four cardboard boxes (10 inches in length, 5 inches in width, and 1.75 inches in depth). the other half are stored in wooden vial racks (figure 1). each individual vial was carefully viewed. handwritten information from labels, storage boxes, and wooden racks was recorded in an excel spreadsheet along with the taxonomic identification for specimens collected. if no taxonomic identification was indicated, insects were identified to the lowest taxonomic level possible using a dissecting microscope along with a variety of dichotomous keys (merritt et al. 2008, stewart & stark 2002, wiggins 1996, thorp & covich 2001) and recorded in a ‘preliminary identification’ column. great care was used while handling specimens, which were not removed from vials (figure 2). after recording each vial’s information, an acid-free card-stock label inscribed with a unique 10-digit serial number (with both a visible and machine-readable data matrix 2d barcode) was inserted. the vial was then placed back into the original box or wooden rack. the locations of the sampled sites were determined using google earth based on locations either indicated on the box or on individual labels inserted in vials. approximate gps coordinates were determined by researching site names and locating the closest road to the site area. most samples were collected from freshwater streams and tributaries in the vicinity around mount st. helens. description of the collection the collection consists of 905 vials of aquatic macroinvertebrates (and a few vertebrates) collected by dr. norman herbert anderson, professor of entomology at figure 1. some of the 903 vials from the collection of dr. norman h. anderson donated to the oregon state arthropod collection in 2018. photo by brandy k. kamakawiwo‘ole oregon state university from 1962-1995. the majority of these specimens were collected from freshwater streams in the vicinity of mount st. helens (wa, usa) following the may 18, 1980 eruption. the dates range from march 29, 1980 to september 8, 1990. some of these specimens may be associated with fusté (1981), anderson & hansen (1987), furnish (1989), meyerhoff (1991), and anderson (1992) but we were not always able to make concrete connections. the collection includes 288 vials from clearwater and elk creeks from 1980-1989 (figure 3). these vials are shown to be connected to richard d. meyerhoff’s (1991) dissertation, “post-eruption recovery and secondary production of grazing insects in two streams near mt. st. helens.” catalog: oregon state arthropod collection vol 6(2) 3 figure 2. vials

brandy k. kamakawiwo‘ole the collection also includes 90 vials from ape canyon, ape creek, and ape tributary from 1980-1987. these vials are shown to be connected to anderson’s (1992) publication: influence of disturbance on insect communities in pacific northwest streams. seventeen samples are from oregon state. two samples are from the h.j. andrews long-term ecological research area in lane county, or (osac_0001220715 and osac_0001220730). thirteen samples are from benton county, or from a stream called berry creek (osac_0001220716 osac_0001220727) and one sample is from oak creek in the same county (osac_0001220731). one sample is from crater lake, or (osac_0001220639). we assumed all other samples were from skamania county in the vicinity of mount st. helens based on labels on boxes. four samples are small vertebrates in the families salmonidae (osac_0001220950) and the orders scorpaeniformes (osac_0001220954) and petromyzontiformes (ammocoete larvae) (osac_0001220394 and osac_0001220710). an additional 15 vials containing specimens collected by luis a. fusté from the muddy river (wa, usa) on march 29, 1980, prior to the eruption are included in this collection. these vials may be associated with fusté’s (1981) publication, “effects of catalog: oregon state arthropod collection 4 vol 6(2) the mount st. helens eruption on the benthic fauna of the toutle river, muddy

evans 1962). the last revisionary work on new world species was by parker (1962; 1964), however literature on the new world fauna has been compiled as part of pulawski’s extensive online checklist (2017). recent interest in historical records of astata spp in oregon and washington by researchers studying biocontrol of halyomorpha halys stål 1855, the brown marmorated stink bug (lowenstein et al. 2018), revealed that few authoritatively identified and vouchered specimen records were readily available for the genus. at the time of this paper, only 61 records for 7 species were available through global biodiversity information facility (gess and ranwashe 2017; gross and oboyski 2017; needham 2017). of these, only a single species, astata nubecula krombein 1952, is reported from oregon and washington based on but 5 specimens (4 from oregon and 1 from washington). the majority of the existing pnw records are of specimens taken in canada’s british columbia, mostly from the southern interior mountains on the border with washington, which likely represent recent surveys by ratzlaff (2015). photographically vouchered observations of astata spp. in the pacific northwest can also be found online, although none are reliably identifiable to species (see photo vouchers below). catalog: oregon state arthropod collection vol 2(1): 1–9 2 osac material the osac has a substantial sphecoid wasp collection due in large part to the research and collecting efforts of herman a. scullen and george ferguson. the astatinae consist of several drawers-worth of material from throughout the world. this paper presents records for the species known from the united states and canada, although records from outside of this area (e.g., mexico) were inlcuded if the the species was reported within the us and canada. parker included these specimen in his published accounts of the distributional range for each species (parker 1962), but only describes the distributions generally and does not provide maps, precise label data, collecting date information or any associated information. ten species are currently reported from the pacific northwest, 8 of which are represented by historical material in the osac (table 1). in total, label data for 316 specimens was transcribed, 187 of which correspond to localities within the pacific northwest (oregon, washington, western canada as well as portions of northern california and western idaho). label data for a. bicolor and a. mexicana are included in the attached dataset, but contain no material collected from the pacific northwest. the specimens in the osac were identified by f. d. parker as part of his revisionary work (parker 1962; 1964) and are thus considered authoritatively determined. these new records will be archived in association with this publication and shared via an ipt server. table 1. specimen records in osac and gbif;

(2007) and stephen et al. (1969). species-level identifications were determined where keys were available for the following genera: agapostemon (stephen et al., 1969), anthophora and ceratina (www.discoverlife.org), bombus (williams et al., 2014), halictus (roberts, 1973), and xylocopa (hurd and moure, 1963). remaining species-level identifications were made by andrew moldenke and lincoln best. no species keys were available for several genera in our region (e.g., lasioglossum (dialictus) and some osmia); specimens in these genera were grouped to morphospecies. catalog: oregon state arthropod collection vol 3(4) 1—12 2 table 1. list of sampling locations within the douglas fire complex (utm 10n) site id number post-wildfire treatment utm coordinates 4 unlogged 10 n 452951 4728980 6 unlogged 10 n 455712 4729922 7 unlogged 10 n 459864 4728947 8 unlogged 10 n 457875 4730556 27 unlogged 10 n 454113 4728147 28 unlogged 10 n 451751 4737841 29 unlogged 10 n 450936 4733986 39 unlogged 10 n 455995 4726212 42 unlogged 10 n 449506 4735955 1 logged 10 n 455434 4728316 3 logged 10 n 457519 4731092 9 logged 10 n 456163 4729656 11 logged 10 n 458417 4734234 26 logged 10 n 455265 4727319 31 logged 10 n 460302 4727944 38 logged 10 n 456793 4726957 41 logged 10 n 447994 4735111 we collected a total 3,561 specimens representing 21 genera and 111 morphospecies of bees. of these, 65 were identified as known species and 46 were grouped by morphospecies (mostly within subgenus lasioglossum (dialictus)). bees of different sexes could often not be matched at the morphospecies level, which inflated the number of morphospecies in our collection. see galbraith et al.

https://dx.doi.org/10.5399/osu/cat_osac.9.1.6109. introduction the composition of caraboid beetle assemblages can be sensitive to forest structure and disturbance, making them a useful indicator taxon for understanding the effects of forest management. early seral forests regenerating from even-aged timber harvests share some structural similarities with those regenerating from natural stand-replacing disturbances. however, the degree to which timber harvests emulate natural disturbance for biodiversity is poorly understood in many temperate forest regions, including the pacific northwest. in this study, we compared caraboid beetle assemblages collected in pitfall traps from early seral forests regenerating from commercial clearcuts, standreplacing wildfire, or post-fire salvage logging across a gradient in stand ages in the klamath mountains of southwest oregon. to gain insight into functional differences among assemblages, we measured several morphological traits on species in our sample. here, we present occurrence data for each species observed in the study, including voucher specimens deposited in the oregon state arthropod collection, and morphological trait data generated from these specimens description of collection sampling we sampled caraboid beetle communities using pitfall traps at a variety of early seral forest sites (stand ages 2 – 20 years) in southwest oregon during the spring of 2019, 2021, and 2022. all forest stands had recently experienced one of three canopy-removing disturbances: clearcut timber harvest followed by herbicide applications on private lands (intensive forest management), stand-replacing wildfire (>75% basal area mortality) on public federal lands, or wildfire with post-fire salvage logging on public federal lands. sampling was conducted as part of a study comparing bee, bird, and caraboid beetle diversity and community composition among early seral forests resulting from these three disturbance treatments (frank 2023). catalog: oregon state arthropod collection vol 9(1) 1—7 2 within each stand, we installed three pitfall trap arrays (plots) with center points at least 100 m apart. each array consisted of four traps, for a total of 12 traps per stand. we installed three traps 12 m from plot center at 0-, 120-, and 240-degree azimuths, and a fourth trap 3 m from center at a 60-, 180-, or 300-degree azimuth. each trap consisted of two nested plastic cups (11.75 cm diameter, 473 ml volume) dug into the ground after removing any duff layer, with the lip of the top cup flush to the soil surface. traps included two cups to facilitate sample collection, and we drilled holes in the lower cup to allow rainwater drainage. we covered traps with plywood squares elevated 2 cm above the soil surface, and used propylene glycol as a preservative liquid. we deployed traps for six weeks beginning april 24 – may 6, except for three stands that were temporarily inaccessible due to late snowfall in spring 2022 and were installed may 17–18. samples were collected after two weeks, and again four weeks later, and were transferred to 95% ethanol immediately upon collection. traps experienced extensive wildlife disturbance, and total sampling effort therefore varies among samples. identification we separated bycatch from caraboid beetles (coleoptera: caraboidea: carabidae, cicindelidae, and trachypachidae). importantly, we included species in our collection that belong to clades that are considered subfamilies of carabidae by some authors, and distinct families by others (bousquet 2012; duran and gough 2020). specifically, we included omus eschscholtz (cicindelidae), clinidium kirby (carabidae: rhysodinae), and trachypachus motschulsky (trachypachidae) in addition to genera that are consistently included in the carabidae (bousquet 2012). caraboid specimens were identified to the finest resolution possible based on morphological characteristics. author j. r. labonte (jrl) made determinations for an initial subset of specimens using lindroth (1961-1969) along with other taxonomic literature, and developed a purpose-built key for identifying the most common species in our samples. this key was used by author g. s. frank (gsf) and undergraduate assistants to determine most of the remaining specimens, consulting jrl on species rarely captured in our study. omus dejeani reiche is readily distinguishable from the other omus species in our sample on the basis of body size alone (pearson et al. 2006), but morphological differences between o. audouini reiche and o. cazieri van den berghe are more subtle. taxonomist m. g. kippenhan determined many of the o. audouini and o. cazieri in our sample based on male aedeagi (van den berghe 1994) and trained gsf on this distinction, but determined external morphological characteristics to be insufficient to distinguish these species in our study area (personal communication). therefore, o. audouini and o. cazieri were identified to morphospecies when males of both species or only females were captured in a stand. harpalus somnulentus dejean and h. opacipennis haldemann were also treated as a single morphospecies. taxonomic names were confirmed with the gbif backbone taxonomy using the rgbif package version 3.7.9 (chamberlain et al. 2024) using program r version 4.2.3 (r core team 2023). we collected a total of 5860 caraboid specimens, representing at least 41 species from 22 genera. occurrence records for all specimens are archived as an attached text file to this publication, including sampling date and approximate locality information. however, the reader is directed to the corresponding author for detailed locality data, sampling effort, and ecological information about each location, including stand age and disturbance treatment category. we selected one voucher specimen for each sex of each species or morphospecies, and deposited these into the oregon state arthropod collection (osac); accession record: osac_ac_2024_08_07-001. catalog: oregon state arthropod collection vol 9(1) 1—7 3 notable records of stomis termitiformis (van dyke) our sample includes five records of a rarely collected species, stomis termitiformis (van dyke, 1926), three of which have been published previously elsewhere (labonte 2022). the two additional records are as follows: oregon: douglas co., 19km s of camas valley, 42.859 °n 123.674°w, 785 m, pitfall trap, 13 v–10 vi 2022, g. s. frank (1, osac, catalog number osac_0001300997). douglas co., 15 km ene of glendale, 42.786 °n 123.591°w, 532 m, pitfall trap, 14 v–13 vi 2021, g. s. frank (1, osac, catalog number osac_0001300994). the records published by labonte (2022) were all in clearcuts. the first of these new records was also from a regenerating clearcut. in contrast, the second of the new records was in a stand burned at high severity in the 2013 douglas complex fire eight years prior to sampling. like the first three records, these records occur further east and at higher elevations than almost all previous state records of s. termitiformis, of which there are few. morphological measurements for a subset of our specimens, we measured morphological characteristics expected to be important predictors of species occurrence among early seral forest stands, based on established connections between morphology and functional traits (forsythe 1987, 1991, ribera et al. 1999, barton et al. 2011, ng et al. 2018). for species captured at least six times, measurements were made on six randomly selected specimens, and we measured all specimens of species with fewer individuals in our sample. all measurements were made using a vhx-1000 digital microscope with 20-200x vh-z20w zoom lens (keyence, itasca, il) and were recorded to the nearest µm. morphological data are archived as an attached text file to this publication. occurrence metadata the occurrence dataset (supplement file 1) contains the following 38 fields, which have been mapped to darwincore biodiversity data standards (https://dwc.tdwg.org/): datasetname: the dataset name, esfb-carabids-osac-2024[version], is included in each record, in case these records are combined with other observational datasets. esfb stands for the early seral forest biodiversity project. basisofrecord: all records refer to a preserved specimen, either pinned or in alcohol. disposition: indicates whether a specimen was accessioned into the osac as part of the voucher collection (‘confirmedpresent’) or not (‘not retained’). specimens not accessioned into osac are retained by the landscape fire and conservation science research group at oregon state university, or in the personal collection of author jrl. catalog: oregon state arthropod collection vol 9(1) 1—7 4 catalognumber: if a voucher specimen for an observation was deposited into the osac, it is provisioned with a unique catalog number, which is presented on a printed label in both arabic human readable digits and a datamatrix barcode. as with the occurrenceid, the catalognumber is represented in the datamatrix as a url: http://osac.oregonstate. edu/sp/osac_xxxxxxxxxx, where the x’s correspond to a unique 10-digit number. observations based on specimens that were not accessioned into the museum (i.e., not retained) were not associated with a catalog number, and the field was left blank. fieldnumber: the specimen id number for this specific project. this identifier begins with a 3-digit stand number (001 – 093), followed by an alphabetic character for the plot within that stand (a, b, or c), the sampling round (1 or 2), and a numeric sequence in the order that a label was created for the specimen. occurrenceid: a globally unique identification number for the observational

after stand-replacing disturbance events can provide important habitat for populations of wild bees, an important group of pollinating insects. however, variability in the abundance and diversity of wild bee communities across different types of early seral forests is poorly understood, and can inform pollinator conservation efforts and sustainable forest management practices. in this study, we compared wild bee assemblages from early seral forests regenerating from three widespread stand-replacing disturbances across a gradient in stand ages in the klamath ecoregion of southwest oregon using blue vane traps. here, we present occurrence data for each bee specimen observed in the study, including voucher specimens deposited to the oregon state arthropod collection. description of collection we sampled wild bee communities using blue vane traps at a variety of early seral forest sites (stand ages 2 – 20 years) in southwest oregon during the 2019, 2021, and 2022 flight seasons. all forest stands had recently experienced one of three canopy-removing disturbances: clearcut timber harvest followed by herbicide applications on private lands (intensive forest management), stand-replacing wildfire (>75% basal area mortality) on public federal lands, or wildfire with post-fire salvage logging on public federal lands. sampling was conducted as part of a study comparing wild bee diversity and community composition among early seral forests resulting from these three disturbance treatments (frank 2023). we set blue vane traps for two-day sampling bouts in late spring mid-summer, with three traps in each forest stand. we filled traps with soapy water, and transferred specimens to 95% ethanol immediately upon collection and into fresh ethanol 1–3 days after collection. bee specimens were determined by author l. r. best to the finest resolution possible using published identification resources and morphological analysis for groups with available resources. bees in the family andrenidae were determined with the aid of laberge (1969, 1975, 1977, 1980, 1985), and timberlake (1956). bees in the family colletidae were determined with the aid of snelling (1966a, 1966b, 1970), and bees in the family halictidae were determined with the aid of gardner and gibbs (2022), gibbs et al (2013), mcginley (1986), and roberts (1973a, 1973b). bees in the family megachilidae were determined with the aid of catalog: oregon state arthropod collection 10 bzdyk (2012), gonzalez and griswold (2013), hurd and michener (1955), rust (1974), sandhouse (1939), sinha and michener (1958), sheffield et al (2011), but see also sheffield (2020) and portman (2023, march 21). bees in the family apidae were determined with the aid of adlakha (1969), brooks (1983, 1988), daly (1973), hurd and linsley (1951), laberge (1956a, 1956b, 1961, 1963), o’brien and hurd (1965), rightmyer (2008), timberlake (1969), and williams et al (2014). keys in michener (2007) were used to support subgeneric determinations within several genera. for groups lacking identification resources relevant to the region and fauna, we used an iterative method supported by coi-mtdna barcoded reference material (ratnasingham & hebert, 2007) and morphological analysis. we sequenced 47 specimens at the canadian center for dna barcoding, resulting in 31 barcode compliant sequences. barcode sequences helped elucidate the identities of 19 species concepts, primarily within the genera lasioglossum and osmia. taxonomic names were confirmed against the gbif backbone taxonomy using the rgbif package version 3.7.9 (chamberlain et al. 2024) using program r version 4.2.3 (r core team 2023). we collected a total of 9909 bees, representing 120 species and all five families found in the state of oregon. ultimately 99.4% of specimens sampled were identified to the species level, 0.5% were identified to subgenus, and the remaining 0.1% (7 specimens) were identified to genus. occurrence records for specimens representing unique combinations of species, sex, and sampling event are archived as an attached text file to this publication, including sampling date and approximate locality information. however, the reader is directed to the corresponding author for detailed locality data, sampling effort, abundance data, and ecological information about each location, including stand age and disturbance treatment category. we selected one voucher specimen for each sex of each species or morphospecies, and deposited these into the oregon state arthropod collection (osac); accession record: osac_ac_2024_02_14-001. metadata the dataset contains the following 38 fields, which have been mapped to darwincore biodiversity data standards (https://dwc.tdwg.org/): datasetname: the dataset name, esfb-bees-osac-2024[version], is included in each record, in case these records are combined with other observational datasets. esfb stands for the early seral forest biodiversity project. basisofrecord: all records refer to a preserved specimen, either pinned or in alcohol. disposition: indicates whether a specimen was accessioned into the osac as part of the voucher collection (‘confirmedpresent’) or not (‘not retained’). importantly, all records are based on preserved specimens examined by taxonomist lincoln best. catalognumber: if a voucher specimen for an observation was deposited into the osac, it is provisioned with a unique catalog number, which is presented on a printed label in both arabic human readable digits and a datamatrix barcode. as with the occurrenceid, the catalognumber is represented in the datamatrix as a url: http://osac.oregonstate.edu/sp/osac_xxxxxxxxxx, where the x’s correspond to a unique 10-digit number. observations based on specimens that were not accessioned into the museum (i.e., not retained) are not associated with a catalog number, and the field was left blank. vol 8(1) 9—14 catalog: oregon state arthropod collection vol 8(1) 9–14 11 fieldnumber: the specimen id number for this specific project, beginning with gsf (initials of the first author), followed by a numeric sequence in the order that a label was created for the specimen. occurrenceid: a globally unique identification number for the observational record. it is cast differently depending on whether the voucher specimen was retained or not. for occurrence records based on specimens now housed in the collection, the occurrenceid has the prefix: ‘http://osac.oregonstate.edu/sp/osac_’ followed by the 10-digit museum-issued catalog number for the voucher specimen, e.g., http://osac.oregonstate.edu/sp/ osac_0001300777. for occurrence records based on specimens not retained in the collection, ‘sp/osac_’ was replaced with ‘obs/[fieldnumber]’, e.g., http://osac.oregonstate.edu/obs/gsf9086. in both cases, these globally unique strings, which are also urls, serve as hyperlinks to access the museum specimen or observation record. eventtype: sample. eventid: a project-specific identifier of a sampling event, formulated as a three-digit site number, plot (a, b, or c), and sampling round (1 or 2), e.g., 046-a-1. this is provided to link specimens collected during the same sampling event. samplingprotocol: the method of sampling. all samples were collected using blue vane traps. eventdate: the range of dates during which blue vane traps were open for a specific eventid. usually a two-day period. recordedby: the names of the field crew that collected contents of each blue vane trap. location: locality data for each specimen are provided in nine fields: countrycode, stateprovince, county, locality, decimallatitude, decimallongitude, geodeticdatum, minimumelevation, and maximumelevation. the locality field is the approximate distance and bearing from the nearest town or other geographic landmark. sampling locations were recorded with high-precision (+/1 m accuracy) gps units. however, these are provided only to the nearest half-degree for publicly shared records to allow for coarse mapping in gbif while also ensuring that detailed uses of the data directly attribute records to the dataset creators (i.e., the authors) rather than the data aggregator (i.e., gbif). similarly, minimumelevation and maximumelevation together provide a 100 m band in which the specimen was sampled. the datageneralization field provides this information for each record, and detailed geolocations are available by contacting the corresponding author. taxon: taxonomic classification of each specimen, checked against the gbif backbone taxonomy, including eight fields: kingdom, phylum, order, family, genus, specificepithet, scientificname, and taxonrank. the scientificname field includes the full binomial with authority and date of publication. the taxonrank field reflects whether a specimen was identified to genus or species. sex: male or female verbatimidentification: a string representing the identification in the original record. includes subgeneric identifications for some specimens not identified to species, in parentheses, and morphospecies groupings unique to this study (e.g., ‘lasioglossum (dialictus) sp. 6’). identifiedby: all specimens were identified by author and taxonomist l. r. best. catalog: oregon state arthropod collection 12 license: a creative commons license

(in prep.). here, we report on and document the deposition of taxonomic voucher specimens (osac_ac_2024_01_30-001), which represent the primary species concepts used throughout hayes et al. (in prep.). specimens were identified to the lowest possible taxonomic level by l. r. best (bees, hymenoptera: apoidea) and j. j-m. hayes (syrphid flies, diptera: syrphidae). the vouchered material includes 139 individual specimens with at least one representative per caste and sex, as available, of 55 species and 14 morphospecies of bees (hymenoptera: apoidea) and 13 species and one morphospecies of syrphid flies (diptera: syrphidae). additional vouchers are included for specimens identified only to the morphospecies level, and megachile brevis say, 1837 individuals that were captured while collecting sections of petals from clarkia amoena (lehm.) a.nelson & j.f.macbr. plants. these 139 voucher specimens come from a much larger dataset, containing over 6,500 observational records of plant-pollinator interactions. introduction planting native flora is a popular practice to conserve pollinators and other wildlife in fragmented landscapes. the number of nurseries that specialize exclusively on native plants, however, is limited (oregon state university survey research center & langellotto, 2023; rihn et al., 2022; white et al., 2018). consumers looking to buy native plants, then, may encounter difficulties sourcing plants (anderson, 2022, 2019; brzuszek et al., 2010) or cultivars of native plants, which are not necessarily representative of wild genotypes (coombs et al., 2020; wilde et al., 2015). research evaluating pollinator use of cultivars, compared to native plants, has yielded mixed results (baisden et al., 2018; a. m. baker et al., 2020; dibble et al., 2020b; nevison, 2016; ricker et al., 2019; torrez et al., 2023; white, 2016), and has yet to explore plant taxa native to the pacific northwest. we thus selected 8 plant species native to the pacific northwest and 18 cultivars of those native plants, to evaluate in a common garden catalog: oregon state arthropod collection vol 8(1) 1—8 2 experiment. we additionally included one popular, exotic plant (lavender, lavandula x intermedia ‘grosso’) in our trial to understand the pollinator communities visiting lavender in gardens. the other goals of our project were to understand if pollinators differentially visit native plants and cultivars, and to identify potential plant traits that may drive pollinator visitation. the focal pollinator groups we explored includes bees (hymenoptera: apoidea), butterflies (lepidoptera: papilionoidea), and syrphid flies (diptera: syrphidae). methods over three field seasons (2020-2022) we vacuum-sampled pollinators from a common garden experiment at the oak creek center for urban horticulture in corvallis, or. additional information about plant establishment, sampling protocols, and methodology can be found in hayes et al. (in prep). pollinators were also recorded, without specimen retention, in some cases. butterflies were collected in a net for identification, and then immediately released. a single honey bee (apis mellifera l.) was collected from each plant during each sample, but remaining individuals were counted and recorded. a single queen bumble bee (bombus flavifrons cresson) was also released in 2022 after taking photographs and adding the observation to inaturalist (hayes, 2022). the voucher material described here are based upon specimens that were collected and retained only (osac_ ac_2024_01_30-001). l. r. best identified bee specimens and j. j-m. hayes identified syrphid fly specimens. specimens were identified to the lowest taxonomic level possible, using taxonomic and identification resources listed in table 1. at least one representative per caste and sex, as available, of each species and morphospecies of collected bees and syrphid flies were curated for deposition in the oregon state arthropod collection in corvallis, or. additional vouchers were included for taxa identified to the morphospecies level and for individuals collecting petals from clarkia amoena plants. a corresponding dataset containing only the vouchered material is presented here. current nomenclature and taxonomic authority for each taxon was obtained using the gbif species matching tool. the dataset contains 49 darwincore fields, including: occurrenceid: a unique identification number and url to the observational record of an individual specimen in the osac museum record. the observational records are not yet connected to the museum’s inventory. for each specimen, the prefix http://osac.oregonstate.edu/sp/osac_ is followed by a 10-digit museum-issued catalog number, e.g., 0001310208, to build the entire occurrence id (e.g., http://osac.oregonstate.edu/sp/ osac_0001310208). catalognumber: a unique catalog number for voucher specimens deposited into the osac collection. the catalognumber is the last portion of specimens’ occurrenceid (e.g., osac_0001310208), and was also printed on a physical label attached to the specimen. fieldnumber: a unique identification number that ties a voucher specimen to a row in hayes et al.’s entire database of collected specimens. the prefix (nnp) indicates specimens collected from the native plant and native cultivar project, which is followed by a four-digit year of collection (2020, 2021, or 2022), and a fouror five-digit collection id (e.g., 00001). disposition: though not all specimens in our study were retained, all vouchered specimens are confirmedpresent. datasetname: hayes_etal_vouchers2023.csv;

arthropod collection. 4(1) p. 1—7. doi: http://dx.doi.org/10.5399/osu/cat_osac.4.1.4650. abstract treehopper insect populations (hemiptera: membracidae) were surveyed in 2018 in benton, josephine, and yamhill counties, oregon to determine their potential roles in the epidemiology of grapevine red blotch virus. stictocephala basalis and tortistilus albidosparsus were identified through a taxonomic assessment of samples collected by hand near vineyards and in a natural area. historical presence of spissistilus festinus in the willamette valley is discussed. voucher specimens were deposited in the oregon state arthropod collection and at the united states national museum of natural history. introduction investigations into potential insect vectors of grapevine red blotch virus (grbv) began at oregon state university in 2016 as a result of scientific breakthroughs in the identification and spatial dynamics of the virus (al rwahnih et al. 2013, dalton et al. 2019). viruses that are vectored by insects are typically transmitted by a narrow taxonomic group (whitfield et al. 2015). the insect species spissistilus festinus (say) (hemiptera: membracidae: smiliinae: ceresini) was determined to be a competent vector of grbv under greenhouse conditions (bahder et al. 2016). museum specimens/records historical records showed the presence of sp. festinus in viticultural regions of northwest oregon, but the most recent finding documented in the oregon state arthropod collection (osac) occurred in 1980, and specimens of sp. festinus from southwest oregon were also decades old (table 1). field surveys insect trapping surveys were conducted in regions of the willamette valley and the illinois valley, oregon, in 2018. the goal was to determine whether populations of potential insect vectors of grbv are currently present in areas of commercial wine grape production. treehoppers were collected in four willamette valley sites and one site near cave junction, oregon.

willamette valley, individuals of stictocephala basalis (walker) (figure 1) were collected by hand as late-instar nymphs in a natural area near corvallis, benton county, and reared to the adult stage for species identification. in yamhill county, specimens of st. basalis were collected as nymphs and adults in three commercial vineyards using hand and vacuum sampling techniques. examples of tortistilus albidosparsus (stål) (figure 2) were collected as nymphs and adults at one of the yamhill county vineyards. in josephine county, adult examples of t. albidosparsus were found and were the only species collected. no populations of sp. festinus were discovered at these sites in 2018. this paper serves to document the deposition of exemplar specimens for these species in a public research collection. specimens were assigned unique identifiers that were then printed as humanreadable and 2d matrix codes on acid free labels affixed to the specimens. in total 34 specimens were deposited in

collection. 5 (1) 1— 12. doi: https://doi.org/10.5399/osu/cat_osac.5.1.4647. abstract the oregon bee atlas is a new volunteer-led effort to characterize the bee fauna of the state of oregon by collecting, preparing, and databasing native bee species and capturing plant host records. in 2018, volunteers collected 11,044 bee specimens across 33 oregon counties, representing 179 unique bee species, and 32 unique bee genera. specimens were collected from a total of 310 unique flowering plant genera, resulting in one of the largest state-level databases of bee-host plant interactions. volunteers produced valuable occurrence records for species poorly known for the state, and species of conservation concern. the 2018 efforts constitute a proof-of-concept of a specimen-focused volunteer native bee survey. introduction the oregon bee atlas (oba) is a volunteer-focused initiative to survey the bee fauna of oregon. the mission of the oba is to train and equip citizen scientists to: (a) create and maintain a comprehensive, high quality and publicly accessible inventory of the state’s native bees and their plant-host preferences, (b) to educate oregonians on the state’s bee biodiversity, and (c) to conduct an on-going survey of native bee populations in order to assess their health. started in 2018 by oregon state university (osu), oregon department of agriculture (oda), and oregon department of forestry (odf), the oba was established as a response to the general lack of knowledge about the status of oregon’s native bees. the state of oregon, located in the pacific northwest (pnw) of the united states, presents unique challenges for detecting changes in native bee populations. these challenges stem from the fact that the state contains 12 distinct ecoregions (level iii, environmental protection agency) that are dissected by two broad mountain ranges, resulting in distinct pollinator communities. although a number of outstanding hymenopterists and pollination biologists have worked on pnw bees, their efforts were primarily based on particular groups of interest and/or specific crops. a general interest in native pollinators and their role in agriculture and ecology in more recent years has kindled an interest and need to examine the regional bee fauna as a whole. early faunistic work on western north american bees centered more heavily on california and other southwestern states (see: michener 1979, p. 238). while moldenke (1976) compared the bee fauna of pacific north america catalog: oregon state arthropod collection vol 5(1) 1—12 2 to that of chile, that work lacks a comprehensive list of species and any means to identify them. since the 1980’s oregon has lagged behind other parts of the us in terms of sampling efforts, with only limited and restricted studies having taken place, many of which were focused primarily on managed lands and/or specific crops (stephen et al. 2009; broussard et al. 2011; kimoto et al. 2012; gonzalez et al. 2013; mciver and erickson 2012; mciver et al. 2009; roof et al. 2018; tubbesing et al. 2014). publicly available records on the global biodiversity information facility show 34% more bee species occurrence records generated east of the 100th meridian than west of it since 1980. (gbif.org 2020). with a few exceptions (e.g., bumblebees), the pnw, and oregon in particular, lack synoptic identification tools or even a solid authoritative checklist for its regional bees. as a result, it can be difficult, if not impossible, to reliably identify even some common taxa. the oba came about as a direct response to this problem, providing a unique, cost effective pathway to generate museum-quality bee specimens from areas that have historically been poorly sampled. unlike similar programs in the united states, the oba uses a largely volunteer workforce to collect and prepare specimens, and to provide entry level taxonomic support. through the framework of the oba, volunteers receive the necessary training to complete these tasks, and are partnered with taxonomists and database managers to ensure quality records are created and maintained. all observational records generated by the oba are based on identified specimens. exemplar specimens are deposited in the oregon state arthropod collection (osac) to facilitate identification into the future, and so they can be used as comparative reference material. all records are made publicly available. in addition to generating quality specimens and vouchered observational records, the oba places a strong emphasis on community engagement and education. on an annual basis, each oba member is required to attend at least one regional outreach event per year, with many attending multiple events. this allows oba members to share project findings and provide information on oregon bees and the problems they face with the general public. here, we present the findings from the first year of the oregon bee atlas (2018), reviewing the spatial distribution of sampling, the species detected, and notable native bee discoveries. methods volunteers volunteer recruitment for the oba has largely drawn from pre-existing groups, such as osu master gardeners, master naturalists, and local beekeepers. efforts were made to advertise training events to these audiences and the general public through extension partnerships, outreach events, social media, and newspaper articles. volunteer applicants were placed in teams based on proximity to training locations. six oregon events, which trained a total of 153 students, were held in the cities of klamath falls, pheonix, grants pass, canby, corvallis, bend, and hood river. trainings took place between june 2017 and february 2018, and in most instances training events lasted one full day. topics covered included: project background, bee biology, insect collection, specimen preparation, and data entry. two additional five-day courses were held on july 9-13 and 16-20, 2018 that covered genus-level identification of native bees in oregon, and species-level identification of bumble bees. catalog: oregon state arthropod collection vol 5(1) 1—12 3 sampling methods and effort two types of sampling were utilized by volunteers: (1) undirected, free sampling, and (2) directed sampling. for undirected sampling, volunteers were encouraged to collect bees often and wherever they chose, either independently or as a team. in directed sampling, volunteer teams were asked to target two types of sites, one with a high level of native flowering plant species, and a second site that was highly managed or disturbed, such as an intensive agricultural or highly urbanized location. teams were encouraged to visit each site roughly every two weeks to observe seasonal variability within bee communities. bees were primarily collected using a variable transect aerial netting, with a small subset collected using blue vane traps (see westphal et al. 2008 for description of each method). volunteers employing aerial netting were encouraged to collect bees from the same host plants into separate killing jars, in order to associate the bees with the host plant. in all cases, however, all sampling conducted within a 1 ha radius of where sampling started was pooled together into a common sample (e.g., aerial netting from a given plant host species growing within a 1 ha area were pooled). all bees caught from a collector within this 1 ha unit, at a given date and time, and where applicable, from a given plant, were provided with a unique identifying number (sample id). observational data entry, specimen preparation, and labeling volunteers recorded the following core data: (a) full name of collector, (b) a sample id identifier, (c) the date and time when sampling was initiated, (d) the name of the closest geographic or civic landmark to the sampling area, (e) latitude and longitude coordinates in degree decimal format, and (f) the number of bees collected. for volunteers installing passive traps, the date and time that traps were removed was also included. when netting was conducted from a specific host plant, the family, genus, and species of the host plant was recorded. volunteer data were recorded using two methods based on volunteer preference. a small number of volunteers used a hand-written field notebook. the majority of oba volunteers, however, used a mobile phone in conjunction with the software package inaturalist (www.inaturalist.org). these volunteers were instructed to photograph and geotag an example of each plant host species that they sampled from, within a given collection area. the image was associated with the inaturalist project (oregon bee project regional teams), allowing additional core data fields to be filled out by volunteers. volunteers then returned home and pinned their specimens, ensuring that each specimen had a temporary label with the sample identification number (sample id). specimen information was either: (a) extracted from the inaturalist project and reconfigured to a spreasheet using a python computer script, (b) input by volunteers or, in a limited number of cases, (c) manually input by oregon bee atlas staff. all data were compiled in a single spreadsheet by oregon bee atlas staff at oregon state university, who also checked each data line for errors, and contacted volunteers for clarification when incorrect or ambiguous data were discovered. records that lacked core data fields (collector name, time and date of collection, location information) were deleted from the final dataset. to ensure standardized and archival labels were placed on all specimens, the final labels were generated at oregon state university on acid free cardstock paper, and then sent to volunteers to place on specimens. label information was pulled from the verified and corrected database using a microsoft word mail merge template and then fed into templates that printed labels on 8.5” x 11” cardstock. these labels were then sent back to volunteers, who were able to place them on the appropriate specimens via their unique field notebook number ([collector name] 18.[sampleid number].[specimennumber]; e.g., lincolnbest18.21.3), which was included on the label itself. catalog: oregon state arthropod collection 4 vol 5(1) 1—12 once specimens were labelled, volunteers worked to provisionally identify and sort their material. they were encouraged to bring material to the oregon bee atlas for monthly open microscope sessions (september-december, 2018) at oregon state university for assistance with genus-level identification. volunteers were instructed to turn their collections into oregon state university by december 21, 2018 for authoritative specimen identification and voucher selection. specimen determinations were made by one of the authors (lincoln best), an experienced taxonomist with the western north american bee fauna. individual volunteer collections were graded by best, based on accuracy of the identification (where applicable), organization, and the skill of specimen preparation. every volunteer who submitted a collection received an individual evaluation grading sheet. voucher material that covered both the taxonomic and geographic breadth of the sampling was accessioned into the oregon state arthropod collection, and excess material was then used to populate species-level reference collections of regional relevance for the volunteer teams. data and metadata once the annual data were collated into a single table, the data and metadata were checked for typographical errors and formatted to conform, wherever possible, to basic darwincore biodiversity data standards (https://dwc.tdwg.org/). the dataset will be made publically available via the osac ipt server (https://osac.oregonstate.edu/ipt) as well as provided as a .csv text file available as a download (supplement 1). the final dataset contains 35 fields: occurenceid: this represents a unique identification number for observational records. occurrenceid is cast differently when specimens are retained. for occurrence records based on specimens housed in the collection, the occurrenceid is given the prefix: http://osac.oregonstate.edu/ followed by ‘sp/ osac_’ followed by the 10 digit museum-issued catalog number for the voucher specimens. for example: http://osac.oregonstate.edu/sp/osac_1234567890. these url’s serve as a hyperlink to access the museum specimen record. observations for which the basisofrecord are not retained, are issued a url with the same prefix, however, the “sp/osac_xxxxxxxxxxx” is replaced with “obs/ oba_”+ [collectorname]+ “:” + [obafieldnumber]. these urls will also retrieve the observation record, but are not tied into the museum’s specimen-based inventory. an example includes: http://osac.oregonstate.edu/obs/oba_stephanie_hazen:18.035.057. catalognumber: a unique catalog number given to a vouchered specimen for an observation deposited into the osac, which is presented on a printed label in both arabic human readable digits and a datamatrix barcode. as with the occurrenceid, the catalognumber is represented in the datamatrix as the url http://osac.oregonstate.edu/sp/osac_xxxxxxxxxx, where the x’s correspond to a unique 10-digit number. disposition: whereas all observational records were based on physical specimens examined by a taxonomist (lincoln best), not all specimens were retained. observations for which a voucher specimen was not retained (e.g., accessioned into the museum) the catalognumber is necessarily left blank and the disposition field indicates ‘not-retained’ as apposed to ‘confirmedpresent’. datasetname: the dataset name “oba_osac_2018” is recorded in each record, in the event that these records are combined with other observational datasets. catalog: oregon state arthropod collection 5 vol 5(1) 1—12 basisofrecord: all observational records in the oba dataset are based on actual pinned specimens, although as noted, not all specimens were archived. fieldnumber: this number string corresponds to the oregon bee atlas information recorded during the initial collecting and specimen submission process. it is important to record in case a record’s history needs to be examined to verify and/or modify a record. bibliographiccitation: each record in the dataset is provisioned with the full bibliographic citation for the dataset, enabling downstream users to cite the record explicitly. doing so provides an easy means to access the source of the data record and attribute proper credit to the creators of those records. license: these data are released under a creative commons license that makes them useable for non-commercial purposes with proper and appropriate attribution (eg., cited using bilbiographiccitation above. details on the license can be found at: http://creativecommons.org/licenses/by-ncsa/3.0/ institutioncode: osac ownerinstitutioncode: osac rightsholder: oregon state university collecting date: the collecting date is stored in two forms and three separate parsed fields: day (131), month (1-12), year (2018); and an eventdate text string, is included if possible for ease of using a date format where that is desirable. locality data: locality data is stored in 6 fields: country, state, county, location, decimallatitude, and decimallongitude. georeferencing was provided by the collector and was either recorded in the field during the collecting event or determined subsequently based on maps and field notes. in all cases, they are recorded in decimal degrees with an accuracy of 3 decimal places (approximately +/100m). samplingprotocol: the collecting method is typically aerial net, where other means were used: eg., sweep net or pan trap, these were indicated. associated plant information: any bees collected in direct association with known plants has this information recorded in one of two ways. if a bee, or bees, were collected directly from a plant while foraging, this is placed into the “associatedtaxa” field, using standard language recommended by darwincore, in which the type of relationship is stated followed by a colon and then the plant taxon, eg., “foraging on” : “ericameria nauseosa”. in cases where a sweep net or pan trap or bees were netted in the vicinity of known plants (e.g., bees were not directly observed visiting floral resources on these plants), this is placed in fieldnotes. recordedby: provides the collector’s name phylum, class, order, family, subfamily, tribe, genus, species, and scientificname; all names were crosschecked against gbif’s species name tool prior to being uploaded. the full binomial with authority and date of publication is provided in scientificname. catalog: oregon state arthropod collection 6 vol 5(1) 1—12 rank: lowest taxonomic rank the record is identified to. sex and caste are recorded if known. repository: the repository is considered osac if voucher material was deposited in the museum. for observations for which the voucher was not retained, this field is left blank. identifiedby and dateidentified: determination information is provided in the identifiedby and dateidentified fields. in all but a few cases, the final 2018 dataset records were determined by lincoln r. best. results volunteers a total of 52 volunteers submitted collections of bees. of the 52 volunteers, approximately 60% submitted collections over 50 bees, 11% submitted collections of more than 500 bees, and two volunteers submitted collections containing over 1,200 bees (figure 1). volunteers were largely based in counties directly west or east of the cascade mountains, with no collectors based in counties in eastern oregon (figure 2). figure 1. the number of bee specimens submitted per volunteer collector in 2018. reference lines indicate 50 and 500 bee specimen levels. catalog: oregon state arthropod collection 7 vol 5(1) 1—12 spatial distribution of sampling native bee specimens were collected from 34 of the 36 oregon counties (figure 3). although specimen collection was spatially uneven across the state, 98.94% of specimens were collected outside of the portland metro area where most of our collectors live. moreover, 36% of specimens were collected east of the cascade mountain range. description of the native bee data volunteers collected 11,044 bees across 33 counties from march 15, 2017 to august 19, 2019. bees were predominantly collected from three bee families, apidae, halictidae, and megachilidae (figure 4). in total, volunteers collected bees from 43 genera, with the most commonly encountered genera baased on specimens being halictus latreille (1,906 specimens), bombus latreille (1,477 specimens), osmia panzer (1,092 specimens), andrena fabricius (991 specimens), and ceratina latreille (957 specimens). there are 179 species listed in the dataset although many specimens from a number of species-rich genera (e.g., andrena fabricius, melissodes latreille and lasioglossum curtis) were only determined to the generic level at the time of publication. we estimate that, once these are identified, the 2018 surveys may ultimately yield examples of over 400 species. figure 2. distribution of where volunteers who submitted collections of more than 50 bee specimens were based in 2018. the color of each county indicates the number of volunteers based in the county. catalog: oregon state arthropod collection 8 vol 5(1) 1—12 notable native bee discoveries this state-wide survey effort produced valuable occurrence records for species poorly known for the region and for species of conservation concern. among the halictidae, agapostemon melliventris cresson was recorded from the alvord desert, and halictus virgatellus cockerell from the alpine in the wallowa mountains. among the megachilidae, ashmeadiella (arogochila) foxiella michener, ashmeadiella (arogochila) timberlakei michener, and ashmeadiella (ashmeadiella) foveata michener were recorded from the high desert, with a. foveata being a novel state species record. the sand dune specialist anthidium palliventre cresson, was recorded from newport, oregon, and the rare hoplitis (proteriades) plagiostoma michener was collected on steens mountain. in the alpine lava fields of mckenzie pass, topotype specimens of atoposmia oregona (michener) were collected from its floral host penstemon davidsonii greene for the first time in oregon in more than 50 years. similarly, new occurrence records for trachusa timberlakei (schwarz) from the cascade range represent the second detection in more than 80 years in oregon. two infrequently detected species, megachile mellitarsis cresson, and hoplitis louisae (cockerell) were recorded from several localities east of the cascades. the apid genus peponapis (say) now relegated to subgeneric status in eucera scopoli, was documented for the first time in oregon in 2018 (best et al. 2019). twenty-one species of bumble bees (apidae: bombus latreille) were recorded including the species of conservation concern bombus caliginosus (frison), bombus fervidus figure 3. heat map of 2018

within the family apidae were produced for ceratina micheneri daly, ceratina neomexicana cockerell, ceratina sequoiae michener, ceratina tejonensis cresson, neopasites fulviventris (cresson), and zacosmia maculata (cresson). description of host plant data a total of 8,812 bee specimens were associated with a plant host (supplement 2). the highest number of specimens were collected from ericameria spp. (5% of plant records), followed by rubus spp. (3% of plant records) and phacelia spp. (2% of plant records). survey across plant genera varied considerably among counties (figure 5). the plant genera from which the most bee species were collected were phacelia, rubus, and penstemon, hosting 50, 47, and 43 unique bee species respectively. discussion the first year of the oregon bee atlas has demonstrated the potential of trained volunteers to provide high quality bee biodiversity data. unlike many other volunteer-based biodiversity surveys (van der wal et al. 2015; dickinson et al. 2010), atlas volunteers surveyed far beyond urban areas, sampling extensively in the sparsely populated area east of the cascade mountains, and locating rare species of native bees. also, unlike most other volunteer native bee surveys where volunteers collect bee photo-vouchers (macphail, gibson, hatfield, et al. 2020; macphail, gibson and colla 2020; falk et al. 2019; josephinecurry jackson

arthropod collection 11 vol 5(1) 1—12 richardson et al. 2019), the oba has demonstrated the feasibility of volunteers to do more technically demanding tasks, such as collecting, preparing, and databasing specimens. moreover, volunteers have largely collected the specimens using active survey techniques, avoiding many of the processing costs and survey biases associated with programs that rely on passive trapping of bees (portman et al. 2020). finally, using an innovative workflow connected to inaturalist plant photo-vouchers, the oba has started to build the most comprehensive bee-host plant databases of any state in the united states. the initial results, which are biased in taxonomic identification effort towards the genus bombus and the family megachilidae, have provided new spatio-temporal data for many of the known species of the state fauna and have detected new state records. there are estimated more than 225 species among specimens not determined beyond the generic level, and this suggests that more than 400 species were collected throughout the state by oregon bee atlas participants in 2018. by refining floral targets and habitats, we predict that future surveys are likely to detect more than 600 species in 55 genera, including new state species, new generic records, and new data for species of conservation concern. the oregon bee atlas will continue to develop and refine its training programs to prepare volunteers to conduct more targeted surveys associated with unique plant communities in oregon, and plans to use historical records to guide volunteers. the atlas’s short-term goal will be to develop a comprehensive checklist of oregon native bees, including range maps. we anticipate that as our knowledge of the occurrence and distribution of native bee species increases in step with a trained cadre of volunteers, oregon will be well positioned to join national efforts to track the long-term population trends of us bee communities. acknowledgement the oregon bee atlas would not be possible without the hard work and dedication of its volunteers (see supplement 3 for a listing of volunteers who contributed to this dataset). we are particularly grateful the oregon bee atlas advisory committee in 2018; tom and julie biddle, judi maxwell, michael o’loughlin, jerry paul, pete and gretchen peterson, nicole sanchez

bee atlas is a new volunteer-led effort to characterize the bee fauna of oregon state by collecting, preparing, and databasing specimens of wild bee species and their plant host records. in 2019, volunteers submitted 25,022 bee specimens across all oregon counties, representing 224 unique bee species and 45 unique bee genera. specimens were collected from a total of 352 unique flowering plant genera, resulting in the largest contemporary state-level database of bee-host plant interactions. volunteers produced valuable occurrence records for species poorly known for the state, and species of conservation concern. the 2019 data builds on the efforts of 2018 in demonstrating the power of a specimen-focused, volunteer wild bee survey. introduction beginning in 2018, the oregon bee atlas has been generating museum-quality bee specimens for the state of oregon (best et al., 2021). the oregon bee atlas (oba) is a volunteer-focused initiative to survey the bee fauna of oregon. the mission of the oba is to train and equip citizen scientists to: (a) create and maintain a comprehensive, high quality and publicly accessible inventory of the state’s wild bees and their plant-host preferences, (b) to educate oregonians on the state’s bee biodiversity, and (c) to conduct an on-going survey of wild bee populations to monitor their health. started in 2018 by oregon state university (osu), oregon department of agriculture (oda), and oregon department of forestry (odf), the oba was established as a response to the general lack of knowledge about the status of oregon’s wild bees. through the framework of the oba, volunteers receive the necessary training to collect and prepare bee specimens and to upload their records through a centralized and standardized database. volunteers are partnered with expert taxonomists and database managers to ensure quality records are created and maintained. all observational records generated by the oba are based on identified catalog: oregon state arthropod collection vol 6(1) 1—13 2 specimens with voucher specimens deposited in the oregon state arthropod collection (osac) so that identifications can be confirmed into the future and used as comparative reference material. all records are made publicly available. here we represent the findings from the second year of the oba, including a review of the spacial distribution of sampling, the species detected, and notable wild bee discoveries. methods methods used in 2019 follow those described in best et al. (2021), with some minor changes. volunteers volunteer recruitment continued through presentations to osu master gardeners, master naturalists, and local beekeepers. recruitment was assisted because of the release of a documentary featuring the oregon bee atlas on march 29, 2019, through the oregon public broadcasting series oregon field guide (https://www.opb.org/news/article/oregon-bee-atlas-project). we conducted eight trainings consisting of 101 students which were held in the cities of corvallis, grants pass, la grande, mcminnville, mosier, portland (x2), and st helens. training took place between november 2018 and march 2019 and in most instances training events lasted one full day. topics covered at training events included: project background, bee biology, insect collection and specimen preparation, and data entry. two additional five-day taxonomy courses were held on july 8—12 and 15—19, 2019 that covered genera-level identification of most common wild bees in oregon, with species-level identification for bumble bees. sampling methods and effort unlike 2018, volunteers in 2019 only conducted undirected, free sampling, and directed sampling used the previous year. the reason directed sampling was dropped in 2019 was to better address the tasks of the oregon bee atlas at this stage, namely, to detect bee species and delimit their range in oregon. as described in best et al. (2021), bees were primarily collected using a variable transect aerial netting, with a small subset collected using trap nests, blue vane, or pan traps (see westphal et al. 2008 for description of each method). volunteers conducting aerial netting were encouraged to pool bees sampled from each host plant and to separate those samples into killing jars to document the association of the bees with the host plant. in all cases, however, all sampling conducted within a 1 ha radius of where sampling started was pooled together into a common sample (e.g., aerial netting from a given plant host species growing within a 1 ha area were pooled). all bees caught from a collector within this 1 ha unit, at a given date and time, and where applicable, from a given plant, were provided with a unique identifying number (sample id). observational data entry, specimen preparation and labeling as in 2018 (best et al. 2021), volunteers recorded the following core data: (a) full name of collector, (b) a sample id identifier, (c) the date and time when sampling was initiated, (d) the name of the closest geographic or civic landmark to the sampling area, (e) latitude and longitude coordinates in degree decimal format, and (f) the number of bees collected. for volunteers installing traps the date and time that traps were removed was also included and when netting was conducted from a specific host plant, the family, genus, and species of the host plant was recorded. beginning in 2019, volunteers were provided the option of generating plant host names using fields in inaturalist (see below). catalog: oregon state arthropod collection vol 6(1) 1—13 3 volunteer data continued to be recorded using two methods, namely written notebooks or using inaturalist, although volunteers were strongly encouraged to use inaturalist for records of netted bees. the use of inaturalist to generate location records and plant host records is described in detail in best et al. (2021). as in 2018, we ensured standardized and archival labels were placed on all specimens. the final labels were generated at oregon state university on acid free cardstock paper and then sent to volunteers to place on specimens. label information was pulled from the verified and corrected database and printed using bartender software (seagull scientific, bellevue, washington) on 8.5” x 11” cardstock using a laser printer. unlike 2018, each label was associated with a unique oregon bee atlas field number. the field number consisted of a 7-digit number. it was composed of a prefix year code (19) followed by a 5-digit sequential unique specimen number (e.g., specimen 1918520 is the record of a female agapostemon texanus collected on grindelia stricta by volunteer marty stein in newport, oregon on july 23, 2019). once labeled, volunteers worked to provisionally identify and sort their specimens and were encouraged to bring material to oregon bee atlas for monthly open microscope sessions (september 2019 – february 2020) at oregon state university for assistance with genus-level identification. volunteers were instructed to turn their collections into oregon state university by march 2020 for authoritative specimen identification and voucher selection. specimen determinations were made by three of the authors: lincoln best (various taxa), joe engler (lasioglossum), and briana lindh (melissodes). individual volunteer collections were graded (where applicable) by best based on accuracy of the identification, and quality of specimen preparation. every volunteer who submitted a collection received an individual evaluation grading sheet. feedback was provided on misidentifications and issues with specimen preparation. voucher specimens that covered both the taxonomic and geographic breadth of the sampling were accessioned into the oregon state arthropod collection and excess material was then used to create regionally relevant reference collections for the volunteer teams. data and metadata once the annual data were collated into a single table, the data and metadata were checked for typographical errors and fields were mapped to darwincore biodiversity data standards (https://dwc.tdwg.org/). the final dataset contains the following 38 fields: occurenceid: this is a globally unique identification number for the observational record. it is cast differently depending on whether the voucher specimen was retained or not. for occurrence records based on specimens now housed in the collection, the occurrenceid has the prefix: http://osac. oregonstate.edu/ followed by ‘sp/osac_’ followed by the 10 digit museum-issued catalog number for the voucher specimen, e.g.; http://osac.oregonstate.edu/sp/osac_0001275241. this globally unique string, which is also a url, serves as a hyperlink to access the museum specimen record. observations made from specimens that were not retained as vouchers at the osac, were also issued unique id’s as urls with the same prefix, however the “sp/[catalognumber]” has been replaced catalog: oregon state arthropod collection 4 vol 6(1) 1—13 with “obs/oba_[fieldnumber]”. these will also retrieve a copy of the observation record but are not tied into the museum’s specimen-based inventory: e.g.; http://osac.oregonstate.edu/obs/ oba_1918520. catalognumber: if a voucher specimen for an observation was deposited into the osac, it is provisioned with a unique catalog number, which is presented on a printed label in both arabic human readable digits and a datamatrix barcode. as with the occurrenceid, the catalognumber is represented in the datamatrix as a url: http://osac.oregonstate.edu/sp/osac_xxxxxxxxxx, where the x’s correspond to a unique 10-digit number. observations based on specimens that were not accessioned into the museum (i.e., not retained) are not associated with a catalog number. disposition: whereas all observational records were based on specimens examined by a taxonomist (lincoln best, joe engler or briana lindh), not all specimens were retained. observations for which a voucher specimen was not retained (e.g., accessioned into the museum) the catalognumber is necessarily left blank. the disposition field indicates if a specimen is ‘confirmedpresent’ or ‘notretained’ in the museum. datasetname: the dataset name, oba_osac_2019[version], is recorded in each record, in the event that these records are combined with other observational datasets. basisofrecord: all observational records in the oba dataset are based on actual pinned specimens, although as noted, not all specimens were archived. fieldnumber: this is the oregon bee atlas specimen id number. it is created when the observation is created and a label is issued. bibliographiccitation: each record in the dataset is provisioned with the full bibliographic citation for the dataset, enabling downstream users to cite the record explicitly. doing so, provides an explicit means to access the source of the data record and attribute proper credit to the creators of those records. license: these data are released under a creative commons license that makes them useable for noncommercial purposes with proper and appropriate attribution (eg., cited using bilbiographiccitation above. details on the license can be found at: http://creativecommons.org/licenses/by-nc-sa/4.0/ institutioncode: osac ownerinstitutioncode: osac rightsholder: oregon state university collecting date: the collecting date is stored in two forms, three separate parsed fields: day (1-31), month (1-12) and year (2019); an eventdate is included for ease of sorting by date. locality data: locality data is stored in 6 fields: country, state, county, location, decimallatitude, and decimallongitude. georeferencing was provided by the collector and was either recorded in the field during the collecting event or determined subsequently based on maps and field notes. in all cases, they are recorded in decimal degrees with an accuracy of 3 decimal places (approximately +/100m). catalog: oregon state arthropod collection 5 vol 6(1) 1—13 full georeference data is available via request to the lead author, however publicly shared records were rounded to the nearest integer, so as to provide visualization on gbif mapping, while better ensuring that more detailed uses of the data directly attribute these records to the appropriate source (i.e, the dataset creators, not the data aggregator). this information is provided in each record via the datageneralization field. samplingprotocol: the collecting method is typically aerial net, where other means were used: eg., sweep net or pan trap, these were indicated. associated plant information: any bees that were collected in direct association with known plants had this information recorded in one of two ways. if a bee or bees were collected directly from a plant while foraging, this information is placed into the “associatedtaxa” field, using standard language recommended by darwincore, in which the type of relationship is stated followed by a colon and then the plant taxon, eg., “foraging on” : “grindelia stricta”. in cases where a sweep net or pan trap or bees were netted in the vicinity of known plants (e.g., bees were not directly observed visiting floral resources on these plants), this is placed in fieldnotes. additional data and metadata associated with the plant association is available via request to the lead author, including voucher photographs. this information was shared in each record via the informationwithheld field. recordedby: provides the collector’s name taxon: all names were crosschecked against gbif’s species name tool prior to being uploaded. fields included are: phylum, class, order, family, subfamily, tribe, genus, and species. the full binomial with authority and date of publication is provided in scientificname. rank: lowest taxonomic rank the record is identified to sex and caste are recorded if known. repository: the repository is considered osac if voucher material was deposited in the museum. for observations for which the voucher was not retained, this field is left blank. determination information: identification data is provided in the identifiedby and dateidentified fields. in all cases, the final 2019 dataset records were determined by lincoln r. best, joe engler or briana c. lindh. findings/results volunteers a total of 128 volunteers submitted collections of bees, with approximately 60% submitting collections over 50 bees, 10% submitting collections more than 500 bees, and 5% submitting collections over 1,000 bees submitted. catalog: oregon state arthropod collection 6 vol 6(1) 1—13 spatial distribution of sampling wild bee specimens were collected from all 36 oregon counties (figure 1). although specimen collection was spatially uneven across the state, 97% of specimens were collected outside of the multnomah county where most of our collectors live. moreover, 33% of specimens were collected in the four ecoregions (level iii) east of the cascade mountain range (figure 2). description of the wild bee data volunteers collected 25,022 bees from march 02, 2019 to december 23, 2019 (figure 3). bees were predominantly collected from four bee families, apidae, halictidae, megachilidae, and andrenidae (figure 4). in total, volunteers collected bees from 45 genera, with the top five collected genera being andrena (3,705 specimens), bombus (3,517), lasiglossum (3,259), osmia (2,784), and halictus (2,465) (figure 4). there are 224 species listed in the dataset although many specimens from a number of species-rich genera (e.g., andrena, melissodes and lasioglossum) were only determined to the generic level at the time of publication. we estimate that more than 400 species were collected by volunteers in 2019. a species abundance curve of volunteer collections suggests that further sampling effort is required to detect all the species in state (figure 5). notably, volunteers identified 31% of their figure 1. heat map of 2019 volunteer sampling effort. each dot represents a distinct sample event, which is a distinct collection within a specific bounded 1 ha area on a given date and time. the increasing red color of the county corresponds to the total

their species level determinations had notable errors (77% correct). notable wild bee discoveries this state-wide survey effort produced valuable occurrence records for species poorly known for the state, and species of conservation concern. among the megachilidae, new state records include ashmeadiella altadenae michener, 1936, ashmeadiella prosopidis (cockerell, 1897), hoplitis boharti (timberlake & michener, 1950), hoplitis emarginata (griswold, 1983), and hoplitis remotula (cockerell, 1910). a. altadenae, h. boharti, and h. remotula have demonstrated fidelity to plagiobothrys (boraginaceae), while h. emarginata have only been recovered from sedum (crassulaceae), with a documented preference for species with cream-colored inflorescences. one record of the adventive exotic species pseudoanthidium nanum (mocsáry, 1881) is provided from troutdale, which adds to a short but growing number of records known from the greater portland area. the oregon bee atlas continues to generate species occurrence data with floral associations for species of conservation concern including 25 records from 10 plant genera for bombus occidentalis greene, 1858, and 9 records from 4 plant genera for bombus morrisoni cresson, 1879. twenty-one species of bombus are documented in this dataset. three additional records are provided for the squash bee, eucera (peponapis) pruinosa (say, 1837), expanding its known range into the willamette valley. figure 2. . map of 2019 volunteer sampling effort by ecoregion (level iii). each dot represents a distinct sample event, which is a

state arthropod collection 11 vol 6(1) 1—13 the minute arizona small carpenter bee, ceratina arizonensis cockerell, 1898, is new to oregon. this species and several other new state records are known only from the vicinity of eight dollar mountain, a significant botanical area known for high rates of endemism. our early survey results support this phenomenon being shared with the pollinator fauna, with several suspected novel bee species awaiting further study. description of host plant data a total of 16,755 bee specimens were associated with 350 unique genera of flowering plant hosts, within 80 families (supplement 2). the greatest number of specimens were collected from ericameria spp. (5% of plant records), followed by phacelia spp. (4% of plant records) and salix spp. (4% of plant records). surveys across plant genera varied considerably among counties (figure 6). the plant genera producing the greatest bee species richness were phacelia, ericameria, and cirsium, hosting a total of 82, 73, and 64 unique bee species. figure 6. heat map of 2019 volunteer sampling effort. each dot represents a distinct sample event, which is a distinct collection within a specific bounded 1 ha area on a given date and time. the increasing green color of the county corresponds to the total number of plant genera that bees were caught from in the county (with totals appearing in the center of each county). catalog: oregon state arthropod collection 12 discussion the second annual cycle of the oregon bee atlas continues to demonstrate the potential of volunteers to create contemporary records of wild bees and their plant hosts on a state-wide level. to our knowledge, the oregon bee atlas remains unique with respect to the number of collectors and the quality of the material they collected, but also in terms of the large extent of plant-host associations. results suggest considerable return of high value data from lethal sampling that would otherwise not be captured by lower intensity non-lethal sampling or sentinel plant monitoring, as advocated by tepedino and portman (2021). these results, which are biased in taxonomic identification effort towards the genus bombus and the family megachilidae, have provided new spatio-temporal and floral data for much of the state fauna, and have detected new state records and suspected new species. nearly 300 species from 47 genera have been identified among the specimens produced from 2018 and 2019. it is estimated that more than 250 additional species remain among unidentified specimens from this field season. it is estimated that during the 2019 field season, volunteers produced specimens representing nearly 500 species. investing additional morphological and molecular resources to unassessed genera is expected to increase our state fauna to nearly 700 species among at least 55 genera. there has recently been a call by portman et al. (2020) for a targeted approach to bee monitoring that includes key ecological information such as associated host plant records. compared to 2018, volunteers continued to collect a high number of specimens that are associated with host-plant records. approximately 67% of our bee occurrence records in 2019 were associated with a host plant. moreover, more of the plant host records, compared to 2018, also exist in a photo vouchered format in inaturalist. in 2020, we changed our protocols to ensure that all plant host records were recorded with a photo-voucher in inaturalist. the bee plant-host dataset we describe here is one of the largest published. our 2019 data alone, for example, exceeds the number of bee plant-host interactions from a great plains region survey (vilella-arnizaut et al. 2021) by 1.7 times, with 3 times the number of plant genera recorded in our network. such datasets can be of high value to identify key forage plants for restoration efforts (e.g., cane and love, 2016; purvis et al., 2021). the oregon bee atlas will continue to develop and refine its training programs to prepare volunteers to conduct more targeted surveys associated with unique plant communities in oregon and use historical records to guide volunteers. beginning in 2020, we conducted a large overhaul in our training program and created the master melittologist program, the first master certificate program in the extension service dedicated to the study of wild bees. acknowledgement the oregon bee atlas would not be possible without the hard work and dedication of its volunteers (see supplement 3 for a listing of volunteers who contributed to this dataset). we are particularly grateful for the oregon bee atlas advisory committee in 2019; judi maxwell, missy martin, michael o’loughlin, jerry paul, pete and gretchen peterson, nicole sanchez, and bonnie shoffner. we are grateful to the foundation for food and agriculture research pollinator health fund and oregon department of agriculture for supporting the oregon bee atlas. vol 6(1) 1—13 catalog: oregon state arthropod collection vol 6(1) 1—13 13 references best, l.r., c. feurborn, j. holt, s. kincaid, c.j. marshall, a. melathopoulos and s. robinson. 2021. oregon bee atlas: native bee findings from 2018. catalog: oregon state arthropod collection. doi: http://dx.doi.org/10.5399/osu/cat_osac.5.1.4647. cane, j.h. and b. love. 2016. floral guilds of bees in sagebrush steppe: comparing bee usage of wildflowers available for postfire restoration. natural areas journal, 36(4), pp.377-391. portman, z.m., b. bruninga-socolar and d.p. cariveau. 2020. the state of bee monitoring in the united states: a call to refocus away from bowl traps and towards more effective methods. annals of the entomological society of america 113(5), pp. 337–342. purvis, e.e., l.r. best, and p. galpern. 2021. identifying key forage plants to support wild bee diversity and a species at risk in the prairie pothole region. insect conservation and diversity, 14(6), pp. 851-861. tepedino, v.j. and z.m. portman. 2021. intensive monitoring for bees in north america: indispensable or improvident? insect conservation and diversity, 14(5), pp. 535-542. vilella-arnizaut, i.b., h. nottebrock, c.b. and fenster. 2021. quantifying habitat and landscape effects on composition and structure of plant-pollinator networks in the us northern great plains. biorxiv. https://doi.org/10.1101/2021.02.12.431025 westphal, c., r. bommarco, g. carré, e. lamborn, n. morison, t. petanidou, s.g. potts, s.p. roberts, h. szentgyörgyi, t. tscheulin and b.e. vaissière. 2008. measuring bee diversity in different european habitats and biogeographical regions. ecological monographs, 78(4), pp.653-671.
