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.

Discover our maps and data. Find recently verified sightings, or search and browse the sightings database.

Learn more about this project. We aim to fill the needs of scientists and nature observers by bringing verified occurrence and life history data into one location.

Get help identifying a butterfly, moth, or caterpillar. It is a trade: you help us collect verifiable data, and we will try to identify the species.
