Identify a Butterfly, Moth, or Caterpillar

With a Photograph

If you have a photograph and you know the date and exact location where the photograph was taken, you can submit your sighting to us and we might be able to help. First, you will need to register for a free account, which is quick and easy to do. Then, submit your sighting. If a regional coordinator can identify the species you saw, your sighting will be added to the database, and you will receive an e-mail containing the identification information. Your submission will contribute to our species profiles, checklists, and database. Concerns? See our privacy policy for more information.

Do you have a photograph of a caterpillar? If so, please provide us with host plant information, or even consider raising it to the adult stage before submitting photographs. Surprisingly, most of the larval stages of butterflies and moths are simply unknown, and caterpillar photographs are very difficult to identify.

Without a Photograph

If you do NOT have a photograph or you do not want to create an account and submit your sighting, start by browsing image thumbnails in the Image Gallery. Use the filters to narrow your search.

Cannot find your species using the Image Gallery? Try the Identification Tools, where you will find additional identification resources, including web and text resources for butterflies, moths, and caterpillars.
