Here we provide a downloadable tableas of the Ecdysis Foundation arthropod collection which includes the The Mark F. Longfellow Ecological Reference Collection (indicated by archival columns). Images are provided as publically accessible links.

Identifications are given either as "reviewed" by our Entomologists or as identified by our artifical intelligence (AI) system. The reviewed column is set to True if the image has been reviewed, or False if the identification was generated by AI. Collection date, and generalized location information is provided. If more than one image is provided for a specimen, this can be determined using the column, 'specimen_id'. We update these files periodically. The date and time the file is generated is included in the filename of the download.

You can learn more about the Ecdysis Foundation Collection and how specimens are collected and utilized at our homepage.
