Butterflies and Moths of North America

collecting and sharing data about Lepidoptera

Explore the variety of moths and butterflies in North America. Choose a region to find photographs, Top 20 species, and regional species checklists.

Get involved in the project. Submit photographs of your sightings, or share your expertise and help us review and verify submissions.
