Caterpillar Identifier by Photo
Upload a clear caterpillar photo for tentative species or family suggestions, visible field marks and lookalikes. The result can discuss a possible adult moth or butterfly, but it cannot establish whether an animal is safe to handle.

Photograph visible field marks
Use zoom to capture the whole animal without touching it. A side view can show body pattern and prolegs; a top view may show stripes or spots. Keep the host plant and location in your own notes for expert confirmation.
Treat suggestions as candidates
Young caterpillars can look different from later stages. Some unrelated species share colors and patterns. If the image lacks distinguishing features, a family-level suggestion or an explicit unknown is more useful than a forced species name.
Understand the possible adult stage
A proposed caterpillar identity may point toward a moth or butterfly, but that relationship depends on the candidate being correct. The tool labels adult-stage suggestions as conditional and does not generate a supposed reference photograph.
Avoid handling unfamiliar caterpillars
Some caterpillars have irritating or venom-bearing hairs and spines. Appearance alone does not establish handling safety. Observe from a distance; seek medical or poison-center advice after a concerning exposure, especially if symptoms develop.

Frequently Asked Questions
Can it tell what butterfly a caterpillar becomes?
It may suggest an adult stage for a supported candidate. An uncertain caterpillar identity also means an uncertain adult identity.
Is a fuzzy caterpillar safe to touch?
The tool cannot determine that. Avoid touching unfamiliar caterpillars or their hairs and spines.
What if the image is blurry?
The result should say which features are missing and suggest a clearer photo rather than force a species name.
Is the web tool free?
It offers a limited number of free analyses. The uploader shows the remaining allowance or the limit message.
