Morpho peleides, the Peleides blue morpho, common morpho or the emperor is 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. The wingspan of the blue morpho butterfly ranges from 7.5–20 cm (3.0–7.9 in). The entire blue morpho butterfly life cycle, from egg to adult is only 115 days.
