Diastatidae are a family of flies, and are in the order Diptera. They occur primarily in the Holarctic Region, but several species are known from the Oriental, Neotropical, and Australasian regions. Members of the family number over 20 described species in three genera. There is an additional fossil genus.[1]

For terms see Morphology of Diptera

Minute flies with grey or brown-grey body and, usually, maculate wings. The postvertical bristles on head are cruciate and vibrissae are present on the head are present.The front orbital bristles are inset and upswept. The costa is interrupted near the end of Radial vein 1 and sometimes also near the humeral crossvein. The subcosta is incomplete fusing with Radial vein 1 before the apex. The posterior basal wing cell and discoidal wing cell are separate. The anal cell of wing and the anal vein of wing are both present.


Adults of living forms have been found along margins of bogs, marshes, and the edges of moist woodlands. Immature biologies are largely unknown. Hennig wrote about it thought to be Campichoeta punctum.

Diastatidae were once considered by some to be Ephydridae.

The Acalyptratae or Acalyptrata are a subsection of the Schizophora, which are a section of the order Diptera, the "true flies". In various contexts the Acalyptratae also are referred to informally as the acalyptrate muscoids, or acalyptrates, as opposed to the Calyptratae. All forms of the name refer to the lack of calypters in the members of this subsection of flies. An alternative name, Acalypterae is current, though in minority usage. It was first used by Justin Pierre Marie Macquart in 1835 for a section of his tribe Muscides; he used it to refer to all acalyptrates plus scathophagids and phorids, but excluding Conopidae.

The confusing forms of the names stem from their first usage; Acalyptratae and Acalyptrata actually are adjectival forms in New Latin. They were coined in the mid 19th century in contexts such as "Muscae Calyptratae and Acalyptratae" and "Diptera Acalyptrata", and the forms stuck.The Acalyptratae are a large assemblage, exhibiting very diverse habits, with one notable and perhaps surprising exception: no known acalyptrates are obligate blood-feeders (hematophagous), though blood feeding at various stages of the life history is common throughout other Dipteran sections.


The Camillidae are a family of flies, or Diptera. The family has five genera (four living; one fossil).


Campichoeta are a genus of flies, and are in the family Diastatidae.


Campichoetidae is a small family of acalyptrate Diptera with only one genus Campichoeta Macquart, 1835. They are regarded by most authors as Diastatidae as subfamily Campichoetinae.


The Chironomoidea are a superfamily within the order Diptera, suborder Nematocera, infraorder Culicomorpha. This superfamily contains the families Chironomidae, Ceratopogonidae, Simuliidae, and Thaumaleidae. One of the more important characteristics used to define them is the form of the larval mouthparts.


The Curtotonidae or quasimodo flies are a small family of small grey to dark brown humpbacked flies (Diptera) with a worldwide distribution, but with very few species in the Nearctic, Australasian/Oceanian, and Palaearctic regions. Most members of the family are found in tropical to subtropical latitudes in Africa and the Neotropics. Many remain undescribed in collections, since little work on the family has been done since the 1930s.

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, including Ochthera.

The petroleum fly, Helaeomyia petrolei, is the only known insect whose larvae live in naturally occurring crude petroleum. Another notable species is Ephydra hians which lives in vast number at Mono Lake.


The Ephydroidea are a superfamily of muscomorph flies.


Euthychaeta is a genus of flies in the Diastatidae family.


Odiniidae is a small family of flies. There are only 58 described species but there are representatives in all the major biogeographic realms.

Life histories are known for only few species of Odinia, and no biological information is available for the majority of species in the family. Known odiniid larvae live in the tunnels of wood-boring larvae of Coleoptera, Lepidoptera, and other Diptera and function as scavengers or predators of the host larvae. One species, Turanodinia coccidarum Stackelberg, has been reared from the egg masses of Pseudococcus comstocki Kuwana, a mealybug.


Oestroidea is a superfamily of Calyptratae including the blow flies, bot flies, flesh flies, and their relatives.The superfamily includes the families:


Mesembrinellidae (formerly included in Calliphoridae)



Rhiniidae (formerly included in Calliphoridae)






Superfamily Tabanoidea are insects in the order Diptera.


The Tephritoidea are a superfamily of flies. The following families are included:

Pallopteridae — flutter flies

Piophilidae — skippers

Platystomatidae — signal flies



Tephritidae — fruit flies

Ulidiidae (Otitidae) — picture-winged fliesThe Tachiniscinae, formerly ranked as the family Tachiniscidae, are now included in the Tephritidae.


The Tipulomorpha are an infraorder of Nematocera, containing the crane flies, a very large group, and allied families.

One recent classification based largely on fossils splits this group into a series of extinct superfamilies (below), and includes members of other infraorders, but this has not gained wide acceptance.
