Firefly-mimicking moth (Arctiidae: Lithosiinae: Rhabdatomis sp.) from Costa Rica. Why mimic a firefly? Because some of them (Lampyridae, actually beetles) contain a potent class of toxins called lucibufagins and so are avoided by many predators - thus, the moth reaps the benefits of decreased predation without actually being toxic.
Wasp-mimicking tiger moth, Isanthrene felderi (Arctiidae), from Monteverde, Costa Rica. This remarkable mimicry is established with yellow and black warning coloration, falsely "membranous" wings, and wasp-like antennae - a very convincing combination.
Not all moths try to blend in; some are rather boldly patterned, like this Josiomorpha species (Arctiini) from Monteverde, Costa Rica.
