The "owl butterflies," so called because of the large eyespots on the ventral surface of the hindwing, which when presented upside down with the wings spread suggest the head of an owl. It is not evident that the butterflies exhibit a behavior that would present such a view to potential predators. In "nature" they occur in neotropical forest understorey, where they frequently perch on tree trunks with their wings held together over their backs and heads upwards.

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
