The Drepanidae are a family of moths with about 1000 species recorded worldwide. They are generally divided in three subfamilies (Minet and Scoble, 1999) which share the same type of hearing organ. Thyatirinae, previously often placed in their own family, bear a superficial resemblance to Noctuidae. Many species in the Drepanid family have a distinctively hook-shaped apex to the forewing, leading to their common name of hook-tips. The larvae of many species are very distinctive, tapering to a point at the tail and usually resting with both head and tail raised. They usually feed on the leaves of trees and shrubs, pupating between leaves spun together with silk.
