Identify a Butterfly, Moth, or Caterpillar

If you have a photograph, you can submit your sighting to us, and we might be able to help. You will need to register for an account, but it is quick and easy to do. See our privacy policy for more information. You will also need to know the date and exact location where you took the photograph. If a regional coordinator can identify the species you saw, your sighting will be added to the database. Your submission will contribute to our species profiles and checklists.

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.
