Hemeroplanes triptolemus
Hemeroplanes triptolemus is a moth of the Sphingidae family. It is known from Costa Rica, Belize, Mexico, Guatemala and probably flies throughout Central America into Colombia, Ecuador, Bolivia, Argentina, Venezuela and Guyana.
The larvae feed on Mesechites trifida. In its larval form, the Hemeroplanes triptolemus is capable of expanding its anterior body segments to give it the appearance of a snake, complete with eye patches. This snake mimicry extends even to the point where it will harmlessly strike at potential predators.
