Diptera Scientific classification Kingdom: Animalia Phylum: Arthropoda Class: Insecta Subclass: Pterygota Infraclass: Neoptera Superorder: Endopterygota Order: Diptera
Diptera (di - two, ptera - wings), or true flies, is the order of insects possessing only a single pair of wings on the mesothorax; the metathorax bears a pair of drumstick like structures called the halteres, the remnants of the hind wings. It is a large order, containing an estimated 240,000 species, although under half of these (about 120,000 species) have been described . It is one of the major insect orders both in terms of ecological and human (medical and economic) importance. The Diptera, in particular the mosquitoes Culicidae, are of phenomenal historical and current importance as disease transmitters, acting as vectors for malaria, dengue, West Nile Virus, yellow fever and other infectious diseases. The study of the Diptera is called dipterology.
Diptera include flies, mosquitoes, maggots, gnats and midges. In compound names containing "fly" for members of this order, the name is normally written as two words, as in "crane fly", though there are a few historical exceptions, such as "sandfly" and "blackfly". For insects that are members of other orders the name should always be written as a single word such as in "butterfly", "scorpionfly".
Ecology and life history
Diptera are a diverse order with an enormous range of ecological roles. Every type of trophic level pattern can be seen in the Diptera. Dipteran predators include the robber fly (Asilidae) . A variety of herbivores can be found in the Diptera, such as the economically important fruit flies (Tephritidae). Flies are often parasites, including internal parasites endo- such as the bot fly and external parasites ectoparasite such as the mosquito, black fly, sand fly or louse fly. Myiasis is the special term for flies infecting living tissue (such as the screw worm fly. Many flies eat dead organic matter detritovores, plant or animal remains. This is especially common in the larval stage, seen in the filter-feeding mosquitoes and black flies to the dung-feeding blow flies (Calliphoridae) or the organic deposit feeding rat-tailed maggot.
The basic fly life cycle is egg, larvae, pupa and adult (winged stage), called holometabolism. There is often a different in food sources for larvae versus adult dipterans of the same species. For example, [mosquito] larvae live in standing water and feed on detritus while the adults feed on nectar as their energy source while females utilize blood as their energy source for egg production.
CSIRO provides an introduction to the external anatomy of the Diptera. Various species are secondarily wingless (especially in the superfamily Hippoboscoidea, or those that are inquilines in social insect colonies).
There are two generally accepted suborders of Diptera. The Nematocera are usually recognized by their elongated bodies and feathery antennae as represented by mosquitoes and crane flies. The Brachycera tend to have a more roundly proportioned body and very short antennae. A more recent classification has been proposed in which the Nematocera is split into two suborders, the Archidiptera and the Eudiptera, but this has not yet gained widespread acceptance among dipterists.
- Suborder Nematocera – long antennae, pronotum distinct from mesonotum. In Nematocera larvae are either eucephalic or hemicephalic and often aquatic.
- Suborder Brachycera – short antennae, the pupa is inside a puparium formed from the last larval skin. Brachycera are generally robust flies with larvae having reduced mouthparts.
- Infraorders Tabanomorpha and Asilomorpha – these comprise the majority of what was the Orthorrhapha under older classification schemes. The antennae are short, but differ in structure from those of the Muscomorpha.
- Infraorder Muscomorpha – (largely the Cyclorrhapha of older schemes). Muscomorpha have 3-segmented, aristate (with a bristle) antennae and larvae with three instars that are acephalic (maggots).
Beyond that, considerable revision in the taxonomy of the flies has taken place since the introduction of modern cladistic techniques, and much remains uncertain. The secondary ranks between the suborders and the families are more out of practical or historical considerations than out of any strict respect for phylogenetic classifications. (Modern cladists tend to spurn the use of Linnaean rank names.) Nearly all classifications in use now, including this article, contain some paraphyletic groupings; this is emphasized where the numerous alternative systems are most greatly at odds.
Current suborders and families
There are two suborders: the Nematocera divided into 77 families of which 35 are extinct ( fossil only ) and the Brachycera with 141 families of which 8 are extinct. See Families of Diptera.
Obsolete names in diptera
There are many names at the family level or above that have been used historically, even some of recent vintage, that are already obsolete or simply not recognized or universally accepted by the dipterological community. For a rather exhaustive list of such names (esp. for those readers who may be wondering why they cannot find a familiar name), please see the List of obsolete names in Diptera.

Band 1 Handbuch, by Lindner himself, contains a history of dipterology, with sections on morphology, physiology and taxonomy with a key to families and short notes on each. The work is finished and almost all parts are out of date but it remains the essential work.
- Faune de France Lechevalier, Paris. The many parts of this work are listed on the publishers website . Less comprehensive than Lindner and , similarly, out of date but more convenient to use. The best parts are Parent on Dolichopodidae and Séguy’s large part 28 on Muscidae (including Anthomyiidae) Scathophagidae and Acalyptratae).
