Thaumaleidae, the solitary midges or trickle midges, are a group of nematoceran flies related to the Ceratopogonidae, Chironomidae, and the Simuliidae. They are small, stocky, yellow to brown flies (3-4 mm). Very few species are known for this family (about 120 species in five genera). Larvae are found in films on rocks and the nonfeeding adults are usually found on foliage along the same streams in which the larvae are found. A few solitary midges are found in the Southern Hemisphere, but Thaumaleidae are generally an Holarctic family. ==Description== Adults are recognised by the seven veins reaching the margin, the costa running around the entire margin, the absence of ocelli, and particularly by the short antennae which are no longer than the head. Larvae resemble larval ''Lutzomyia'' (Psychodidae), ''Forcipomyia'' (Ceratopogonidae), and some Chironomidae. However, unpaired prolegs, a ventrally directed truncate head, and prothoracic spiracles on a short respiratory tube differentiate them.
