The nematoceran family Psychodidae (moth flies or drain flies) are small true flies (Diptera) with short, hairy bodies and wings giving them a "furry" moth-like appearance. The adults have long antennae and the wings are leaf-shaped, either slender or broad, with the most elementary wing venation of any Diptera, having little more than a series of parallel veins without crossveins. Adult Psychodidae are typically nocturnal and associated with damp habitats. The larvae of the subfamilies Psychodinae, Sycoracinae and Horaiellinae live in aquatic to semi-terrestrial habitats, including bathroom sinks; some species are commonly nuisance pests in bathrooms. These pests are commonly removed through use of boiling water, bleach, or drain cleaner. Prevention is best accomplished by removing food sources such as hair clogs in drains.
