Blue morphos butterfly belongs to the Family Nymphalidae, Genus Morpho, and species menelaus. It is a species of neotropical butterfly that has iridescent blue wings. Like most insects, the females are not as brilliantly colored as the males and have a brown edge with white spots surrounding the iridescent blue area. The undersides (visible when the butterfly is resting) are brown with bronze-colored eyespots. Adults drink the juices of rotting fruit. The caterpillar of the blue morpho is red-brown with bright patches of lime-green on the back, and it eats the plant Erythroxylum pilchrum nocturnally (at night). Blue morphos live in rainforests from Brazil to Venezuela.
