Two lake flies observed in Neenah, Wisconsin, after the yearly hatch in Lake Winnebago. The Chironomidae (informally known as chironomids, nonbiting midges, or lake flies) comprise a family of nematoceran flies with a global distribution. They are closely related to the Ceratopogonidae, Simuliidae, and Thaumaleidae.
A midge is any small fly, including species in several families of non-mosquito nematoceran Diptera. Midges are found (seasonally or otherwise) on practically every land area outside permanently arid deserts and the frigid zones.
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).
The Nematocera (the name meaning "thread-horns") are a suborder of elongated flies with thin, segmented antennae and mostly aquatic larvae.This group is paraphyletic and contains all flies except for species from suborder Brachycera [4] (the name meaning "short-horns"), which includes more commonly known species such as the housefly or the common fruit fly.
Meaning "little devil", the diawl bach is a popular Welsh fly pattern used in British still waters, and an appropriate lure to use when the fish are feeding on midge pupae. The dressing is simple: size 8 to 14 hook, brown thread, a few barbs of brown hackle for the tail, copper wire, a few barbs of peacock herl for the body, and tying thread ...
Cecidomyiidae is a family of flies known as gall midges or gall gnats. As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths called galls . Cecidomyiidae are very fragile small insects usually only 2–3 mm (0.079–0.118 in) in length; many are less than 1 mm (0.039 in) long.
The members of the family are sometimes known as frog-biting midges. The family currently consists of just one genus, totalling 115 extant and 10 fossil species worldwide. Most extant species are found in the lower latitudes, usually associated around the tropics. [1] They are tiny flies with a wing length of 0.6-2.5 mm.
Scatopsidae on Impatiens. The minute black scavenger flies or "dung midges", are a family, Scatopsidae, of nematoceran flies.Despite being distributed throughout the world, they form a small family with only around 250 described species in 27 genera, although many await description and doubtless even more await discovery.
