Snap to identify

Our image ID gets better with each photo you add.

LepSnap analyzes your moth/butterfly photo to suggest possible IDs that can be later verified by experts.

Record your observations

Your photos are neatly organized by what they depict.

LepSnap arranges your observations into a dynamic checklist. When taxonomic treatments change, your records update automatically.

Showcase your collection

Sharing collection data builds a richer picture of morphology and distribution.
