Dixidae
The Dixidae (meniscus midges) are a family (biology), family of aquatic insect, aquatic nematoceran fly, flies (Diptera). The larvae live in unpolluted, standing fresh waters, just beneath the surface film, usually amongst marginal aquatic vegetation. They are found in all continents except Antarctica. Description For terms see Morphology of Diptera Dixidae are small (body length not more than 5.0 mm) slender gnats with thin legs. The head is relatively broad. The antennae are thin and the flagellum has 14 segments. The proboscis is short and thick and the palpi are five-segmented. The thorax is slightly convex. The wing veins are without scales (with scales in the closely related family Culicidae. The subcosta is fused with the costa at the level of the base of Rs or slightly proximal to this. The wing venation exhibits radial, medial, and cubital forks (R 4 branched, M 2 branched, Cu 2 branched). R 2+ 3 is strongly arched, the r–m crossvein is distinct, and the discal ce ...

Midge
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. Some midges, such as many Phlebotominae (sand fly) and Simuliidae (black fly), are vectors of various diseases. Many others play useful roles as prey for insectivores, such as various frogs and swallows. Others are important as detritivores, and form part of various nutrient cycles. The habits of midges vary greatly from species to species, though within any particular family, midges commonly have similar ecological roles. Examples of families that include species of midges include: * Blephariceridae, net-winged midges * Cecidomyiidae, gall midges * Ceratopogonidae, biting midges (also known as no-see-ums or punkies in North Americabr>BugGuide/ref> and sandflies in Australia) * Chaoboridae, phantom midges * Chironomidae, non-biting midges (a ...

Nematocera
The Nematocera (the name means "thread-horns") are a suborder of elongated flies with thin, segmented antennae and mostly aquatic larvae. This group is paraphyletic and contains all flies but species from suborder Brachycera (the name means "short-horns"), which includes more commonly known species as housefly or the common fruit fly. Families in Nematocera include mosquitoes, crane flies, gnats, black flies, and a multiple groups of families described as midges. The Nematocera typically have fairly long, fine, finely-jointed antennae. In many species, such as most mosquitoes, the female antennae are more or less threadlike, but the males have spectacularly plumose antennae. The larvae of most families of Nematocera are aquatic, either free-swimming, rock-dwelling, plant-dwelling, or luticolous. Some families however, are not aquatic; for instance the Tipulidae tend to be soil-dwelling and the Mycetophilidae feed on fungi such as mushrooms. Unlike most of the Brachycera, the ...

Johann Wilhelm Meigen
Johann Wilhelm Meigen (3 May 1764 – 11 July 1845) was a German entomologist famous for his pioneering work on Diptera. Life Early years Meigen was born in Solingen, the fifth of eight children of Johann Clemens Meigen and Sibylla Margaretha Bick. His parents, though not poor, were not wealthy either. They ran a small shop in Solingen. His paternal grandparents, however, owned an estate and hamlet with twenty houses. Adding to the rental income, Meigen's grandfather was a farmer and a guild mastercutler in Solingen. Two years after Meigen was born, his grandparents died and his parents moved to the family estate. This was already heavily indebted by the Seven Years' War, then bad crops and rash speculations forced the sale of the farm and the family moved back to Solingen. Meigen attended the town school but only for a short time. He had learned to read and write on his grandfather's estate and he read widely at home as well as taking an interest in natural history.

Morphology Of Diptera
Dipteran morphology differs in some significant ways from the broader morphology of insects. The Diptera is a very large and diverse order of mostly small to medium-sized insects. They have prominent compound eyes on a mobile head, and (at most) one pair of functional, membraneous wings, which are attached to a complex mesothorax. The second pair of wings, on the metathorax, are reduced to halteres. The order's fundamental peculiarity is its remarkable specialization in terms of wing shape and the morpho-anatomical adaptation of the thorax – features which lend particular agility to its flying forms. The filiform, stylate or aristate antennae correlate with the Nematocera, Brachycera and Cyclorrhapha taxa respectively. It displays substantial morphological uniformity in lower taxa, especially at the level of genus or species. The configuration of integumental bristles is of fundamental importance in their taxonomy, as is wing venation. It displays a complete metamorphosis (egg, ...
