Opsiphanes cassina

Opsiphanes cassina, the split-banded owlet, is a species of butterfly belonging to the family Nymphalidae.

Description
The wingspan of female Opsiphanes cassina are roughly 70 mm wide, while males' wingspans are smaller. The uppersides of their wings are dark brown, with yellow-orange bands crossing the forewings and the edges of the hindwings. The undersides of the wings are also brown, with some large eyespots. Adults of this species are only alive for about ten days, in which they have to feed, mate and lay their eggs.

The larvae are bright green, and possess two prong-like protrusions on their rear. Their diet includes Cocos nucifera, Livistona species, Acrocomia vinifera, Bactris guineensis, Erythrea salvadorensis and Roystonea regia. They are also dangerous defoliators of the oil palm.

Distribution
This species occurs from Mexico to the Amazon basin.
