Forest Giant Owl Butterfly -- A group of South & Central America butterflies. The underside of the wings look nothing like the upper wings. The undersides are brown with markings somewhat resembling feathers, and there is a large prominent black spot with a bright yellow ring around it on each lower wing. These spots look like eyes. When the butterfly is threatened, it assumes an upside down pose displaying eyespots. This startles a predator into thinking it is actually a large predatory owl.
