The "dark" owl butterfly (Caligo brasiliensis) is famous for its large, owl-like eyespots on its hindwings, used to deter predators. Native to Central and South America, it is also known as the Brazilian owl, sulanus owl, or almond-eyed owl. This large butterfly is primarily active at dusk, feeding on the juices of fermented fruits like bananas and mangoes. It is found mainly in Brazil, Colombia, Venezuela and Ecuador but also in Trinidad, Honduras, Guatemala and Panama north to Mexico.
