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; Limacodidae: Euclea Hübner, 1819, Isa Packard, 1864, Lithacodes Packard, 1864, 
Monoleuca Grote & Robinson, 1868, Parasa Moore, 1859, Prolimacodes Schaus, 1896, Tortricidia Packard, 
1864; Megalopygidae: Megalopyge Hübner, 1820; and Zygaenidae: Harrisina Packard, 1864 (Table 1).

Additional material from outside of North America is present, but was not digitized and catalogued 
at this time.

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
 
Owing to their relative scarcity in North America and the Pacific Northwest it is not surprising that 
the OSAC possesses few examples of the Zygaenoidea. The vast majority of the holdings belong to 
the family Limacodidae, and a single species in particular: Tortricidia testacea Packard, 1864 which is 
common in the Pacific Northwest. Only a single example of the family Dalceridae is present, and only 
7 examples of the Megalopygidae which are from the American southwest.  Although Oregon has 
a native zygaenid: Harrisina metallica Stretch, 1885, the 20 specimens in the collection were obtained 
in California or elsewhere outside of the Pacific Northwest. The species is reported in southwestern 
Oregon where it can be a pest on grapes and vineyards. Voucher material from Oregon should be 
targeted in the future to ensure the local populations are represented.

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.
