Pterophoridae

Pterophoridae is a family of moths commonly known as plume moths, comprising more than 1,600 species in roughly 95 genera and belonging to the larger group Apoditrysia, most of them small enough to be classed among the microlepidoptera. The family is distinguished by unusually divided wings: the forewings are typically split into two or three feathered lobes and the hindwings into three, an unconventional structure that nonetheless allows effective flight. All plume moths share two rows of club-shaped scales on the underside of the hindwings in both sexes, a feature whose function remains unclear. At rest, plume moths hold their narrow, rolled wings out to the sides, often resembling dried grass, a posture that camouflages them from predators even in daylight.
