Morpho Peleides

[Kollar 1850]

Other names: common morpho, the emperor

An iridescent tropical butterfly found in Mexico, Central America, northern South America, Paraguay and Trinidad. The brilliant blue color in the butterfly's wings is caused by the diffraction of the light from millions of tiny scales on its wings. It uses this to frighten away predators, by flashing its wings rapidly.
