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, [ 1 ] which are attached to a complex mesothorax.
Chaetotaxy is also used in determining homology in certain morphological traits, as well as providing information about the phylogeny between taxa. For example, chaetotaxy has been used to clarify evolutionary relationships in Collembola , [ 1 ] as well as identify new species .
Diptera is an order of winged insects commonly known as flies. Diptera, which are one of the most successful groups of organisms on Earth, are very diverse biologically. None are truly marine but they occupy virtually every terrestrial niche. Many have co-evolved in association with plants and animals.
Psocodea is a taxonomic group of insects comprising the bark lice, book lice and parasitic lice. [2] It was formerly considered a superorder, but is now generally considered by entomologists as an order .
For terms see Morphology of Diptera. Minute (2–3.5 mm or 0.079–0.138 in long), slender, lustrous black flies with hyaline wings. The postvertical bristles on the head are cruciate. There are three small orbital bristles on head on each side of frons, one of which is poorly developed. The vibrissae on the head are well developed.

The male terminalia are figured by Hippa (1968) ). [3] Larva described and figured by Rotheray (1994). [4] See references for determination. [5] [6] [7] [8]
A cecidomyiid laying eggs on grass Cecidomyiid in copula Cecidomyiid oviposting into boreholes of bark beetles on a fallen beech. 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 ...
Ephydridae (shore fly, sometimes brine fly) is a family of insects in the order Diptera. Shore flies are tiny flies that can be found near seashores or at smaller inland waters, such as ponds. About 2,000 species have been described worldwide, [ 2 ] including Ochthera .
