Butterflies and Moths of North America

collecting and sharing data about Lepidoptera

Butterflies and Moths of North America (BAMONA) is an ambitious effort to collect, store, and share species information and occurrence data. You can participate by taking and submitting photographs of butterflies, moths, and caterpillars.

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.
