Morpho achilles (Linnaeus, 1758)

Morpho achilles, the Achilles morpho, blue-banded morpho, or banded blue morpho, is a Neotropical butterfly.

The genus name Morpho comes from the Greek epithet of Aphrodite, goddess of love. Achilles was a Greek hero of the Trojan War, the central character of Homer's Iliad.

In Morpho achilles patroclus, the dorsal sides of the forewings are black, with two broad vertical bands of brilliant blue. The undersides of the hindwings are olive brownish, with several ocelli formed by blue, yellow, and red concentric rings.
