Biblis hyperia

From above, the wings are a dark brown so deep it looks nearly black. On each hindwing a red band runs a little way in from the outer margin, and the hindwing's outer edge is scalloped rather than smooth. An older museum bulletin describes it the same way: a black butterfly whose hindwings are bordered with red.

The sources describe this as a butterfly of tropical America. One gives its range as running from Paraguay north through Central America to Mexico and the West Indies. Another lists Central and South America as where it comes from. In the United States it is described as an occasional resident of the lower Rio Grande Valley in Texas. Individuals sometimes wander farther north, with one source naming central Texas.

Like other butterflies, it goes through four stages: egg, caterpillar, chrysalis and adult. Females lay eggs one at a time or in small groups on fresh new growth. The caterpillar builds itself a small perch. After that it forms a chrysalis, and the adult butterfly comes out of the chrysalis.
