Abstract:

A dataset of 40,007 observational records is presented for North American Lepidoptera belonging to the families: 
Hesperiidae, Papilionidae and Pieridae are presented.  The records represent the majority, but not entire, North 
American holdings of these groups in the collection.  We expect to add more records as well as modify these 
records with time. The dataset is being published at this time in order that the records therein be citable prior to 
being shared online.

Keywords: butterflies, conservation, faunistics, biodiversity data

Introduction:

This publication provides an archived and citable reference 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

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).
