Digitizing Chicagoland Butterflies

Using the Butterflies and Moths of North America web site, we generated a species list of butterflies found in Chicago. We narrowed the list to species that have been collected, sighted, or published in Cook County, Illinois. We pulled the best specimen from each species on the list to publish and were able to find every species on our list. Not every specimen from our collection that we pulled was collected in Cook County. These specimens represent the species that has been found here. Many species are migratory or cosmopolitan.

Funding for this project was provided by Grainger Digital Initiative Fund.
