The Owl Butterflies, genus: Caligo, from the rainforests of Central and South America are named for the dramatic eyespots on the underside of the lower wing, which look much like the large staring eyes of an owl. These eyespots may frighten some potential predators or provide a target that is well away from the head. Most species are rather drab on the upper sides of the wings, in shades of tawny brown or dusky blue.
This butterfly feeds on rotting fruit, and is most active at dawn and dusk, when its awkward flapping flight will remind you of a bat.
