We can help identify your butterfly or moth!
If you know the date and location where the photograph was taken, we can help. It's simple!
A coordinator will review your submission, and you will get an email with the identification.
We will store your submitted data. Your submission will contribute to our species profiles, checklists, and database. You can track all your submissions and create a personal species list.
Identifying Caterpillars
Do you have a photograph of a caterpillar? If so, when you submit your photograph, please provide us with host plant information if possible. 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 can be very difficult to identify. It may take some time for a coordinator to identify your caterpillar.
Please donate!
We depend on donations to keep Butterflies and Moths of North America freely available. We want to express our gratitude to all who showed their support by making a contribution this year. You can donate to support this project at any time.
