Drepanidae

Definition

A family of moths (order Lepidoptera) comprising approximately 660 described species worldwide, characterized by forewings with a distinctively hooked or falcate apex that gives the group its common name "hook-tip moths." The family includes three subfamilies sharing a unique type of hearing organ (tympanal structure); the subfamily Thyatirinae, sometimes historically treated as a separate family, resembles owlet moths (Noctuidae) in general appearance. Drepanidae larvae typically feed on broadleaf trees and shrubs, with some species economically significant as defoliators.

Etymology

From Greek drepane, "sickle," referring to the curved, hook-like wing apex.

Example

The common hook-tip moth Drepana falcataria displays the family’s diagnostic falcate forewing tip and belongs to the nominate subfamily Drepaninae.

Synonyms

• hook-tip moths (common name)

Usage Notes

Formerly broader in some classifications; the subfamily Thyatirinae (false owlet moths) was often separated as family Thyatiridae. Drepanidae is universally accepted at family rank in modern lepidopteran phylogenetics. Not to be confused with Drepaneidae, an unrelated family of ray-finned fishes.
