Psychodidae, common name moth flies, is a family of true flies. Many genera have short, hairy bodies and wings, giving them a "furry" moth-like appearance, hence one of their common names, moth flies. They are also called drain flies, sink flies, filter flies, sewer flies, or sewer gnats because a few species live in drains. Members of the sub-family Phlebotominae, which are hematophagous, may be called sand flies in some countries, although this term is also used for other unrelated flies, such as horse flies (Tabanidae) and no-see-ums (Ceratopogonidae).
