A nocturnal butterfly. The Owl butterfly mostly comes out at dusk and can be active through the night. In the daytime, they often feed on rotten fruit or sleep on tree trunks. This butterfly has the habit of landing on the back of visitors' trousers in our display. The Owl butterfly is programmed to land on vertical tree trunks where it is camouflaged; when there are no trees it settles for the closest-looking thing.
