Eurephan Cracker Moth

Tropical and subtropical forests, river edges, and wooded areas across Central and South America.

Adults primarily feed on rotting fruit, sap from wounded trees, and animal dung rather than nectar. Larvae feed on Euphorbiaceae plants.

Diurnal and highly territorial; males produce a distinct clicking or cracking sound using their wings when startled or defending territory. They typically rest head-down on tree trunks with wings spread flat to camouflage.

Harmless to humans; serves as an important bioindicator of forest health and a food source for insectivorous birds and local predators.
