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.
