Description:This photograph depicts an anterior oblique view of an Io moth, Automeris io, larva.
During its developmental stages, or instars, the Io moth larva undergoes changes, becoming a stinging, or urticating caterpillar. The spines on these larvae are extremely sharp, and release their toxin with very little stimulation. Reactions to the toxin range from a stinging pain and swelling, to anaphylactic shock, and death.
