An eyespot is an eye-like marking. They are found on butterflies, reptiles, felids, birds and fish. Eyespots may be a form of mimicry in which a spot on the body of an animal resembles an eye of a different animal to deceive potential predator or prey species; to draw a predator's attention away from the most vulnerable body parts; or to appear as an inedible or even dangerous animal. In larger animals, eyespots may play a role in intraspecies communication or courtship – the most well-known example is probably the eyespots on a peacock's display feathers. The eye-like markings in some butterflies and moths and certain other insects, as well as the Sunbittern do not seem to serve a mimicry function. In some other cases, the evolutionary function of such spots is also not understood. There is evidence that eyespots in butterflies are antipredator adaptations, either in deimatic displays to startle or scaring off predators, or to deflect attacks away from vital body parts. Butterfly eyespots may also play a role in mate recognition and sexual selection, playing a similar role to the eyespots found on larger organisms mentioned above. Pattern formation of concentric spots is probably less complex than the conspicuous eyespots might suggest; eyespots may simply be morphogenetic "spandrels", not necessarily adaptations.
