Owl Butterfly
Cahuita, Costa Rica (2002).
The owl butterfly is known for it’s huge eyespots, which resemble owls’ eyes. It lives between sea level and 5,250 feet and is occasionally a pest to bananas. Owl butterflies are very large (2.6–7.9 in) and fly only a few meters at a time, so avian predators have little difficulty in following them to their settling place. However, the butterflies preferentially fly at dusk, when few avian predators are around.

"Caligo eurilochus", the forest giant owl, is an owl butterfly ranging from Mexico, through Central America, to the Amazon River basin in South America. The type locality is Suriname. Several subspecies are recognized, but many more have been proposed.
