Drepanidae

Drepanidae is a family of moths in the order Lepidoptera, commonly known as hook-tip moths. The family name derives from the Greek word "drepanon," meaning sickle, referring to the characteristic sickle-shaped apex of the forewing in many species. These moths are distributed worldwide, with a notable diversity in tropical and subtropical regions.

Adult drepanids typically possess stout bodies and broad wings. Their wing patterns vary but often include cryptic coloration that aids in camouflage against bark or foliage. The forewings are generally longer and more triangular than the hindwings. A distinguishing feature, apart from the wing shape, is often the presence of a prominent discal spot on the forewing, though this can be absent in some genera.

The larvae of Drepanidae are usually smooth-bodied and may have a few small tubercles or spines. They are primarily folivorous, feeding on a variety of plants, with specific host plants often being species-specific within certain genera. Pupation typically occurs in a simple cocoon spun among leaves or bark.

Drepanidae is a relatively small family, with around 700 described species. Notable genera include Drepana, Callidrepana, and Habrosyne. While not typically considered major agricultural pests, some species can cause localized defoliation in certain environments. Their study contributes to our understanding of moth evolution and biodiversity within the Lepidoptera.
