I first researched the insect species, reasons for endangerment, and looked at photos, then painted representations on a 2.5x3.5” watercolor card. The common name, Latin name, and status are written on the back of the card; sometimes reasons why the species is struggling are noted.

The painted cards are displayed on glassine envelopes, the type is used for storing insect specimens. The relationship of the card to the envelope signifies the status of the species.
A. Species of Special Concern, the least threatened category, are displayed on top of the envelope.
B. Threatened Species are displayed underneath the envelope flap
C. Endangered species are placed inside the envelope.
D. Extirpated species are inside the envelope. The card is flipped so that the painting is not visible. Extirpated species can be viewed in the Encyclopedia of Extirpation.
