The Brachyceran infraorder Asilomorpha is a large and diverse group of flies, containing the bulk of the nonmuscoid Brachycera. The larvae of asilomorphs are extremely diverse in habits, as well.


Calyptratae is a subsection of Schizophora in the insect order Diptera, commonly referred to as the calyptrate muscoids (or simply calyptrates). It consists of those flies which possess a calypter that covers the halteres, among which are some of the most familiar of all flies, such as the house fly.

About 18,000 described species are in this group, or about 12% of all the flies yet described.


Carnoidea are a superfamily of Acalyptratae flies.


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 Culicoidea are a superfamily within the order Diptera. The following families are included within the Culicoidea:

Dixidae – meniscus midges

Corethrellidae – frog-biting midges

Chaoboridae – phantom midges

Culicidae – mosquitoes


The Culicomorpha are an infraorder of Nematocera, including mosquitoes, black flies, and several extant and extinct families of insects.


The Ironomyiidae, or ironic flies, are a small family of insects of the order Diptera. Historically, they have been included in the family Platypezidae, and includes three extant species and a number of extinct fossil species.


The Lauxanioidea are a superfamily of flies that includes the two large families, the Lauxaniidae and Chamaemyiidae, and the small family Celyphidae. Generally, they are small to medium, densely populated, coloured flies. The Chamaemyiidae and Cremifaniidae live as parasites on insects. The family Celyphidae look like beetles.

Some authors also recognize the family Cremifaniidae, but most place this in the Chamaemyiidae.

List of Diptera families

This is a list of the families of the order Diptera (true flies).


Muscoidea is a superfamily of flies in the subsection Calyptratae. Muscoidea, with approximately 7000 described species, is nearly 5% of the known species level diversity of the Diptera, the true flies. Most muscoid flies are saprophagous, coprophagous or necrophagous as larvae, but some species are parasitic, predatory, or phytophagous.


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)






Platypezidae is a family of true flies of the superfamily Platypezoidea. The more than 250 species are found worldwide primarily in woodland habitats. A common name is flat-footed flies, but this is also used for the closely related Opetiidae which were included in the Platypezidae in former times.Some other genera formerly included here have been recognized as quite more distant and are nowadays placed in the asilomorph family Atelestidae.


The Platypezoidea are a superfamily of true flies of the section Aschiza. Their closest living relatives are the Syrphoidea, which, for example, contain the hoverflies. Like these, the adults do not burst open their pupal cases with a ptilinum when hatching, thus the Aschiza do not have the inverted-U-shaped suture above the antennae. They are, however, muscomorphs, thus have a particular type of pupal case resembling a rounded barrel and called puparium.


Sciaroidea is a superfamily in the infraorder Bibionomorpha. There are about 16 families and more than 15,000 described species in Sciaroidea. Most of its constituent families are various gnats.


Sciomyzoidea is a superfamily of Acalyptratae flies.

The families placed here are:

Coelopidae – seaweed flies






Sepsidae – scavenger flies

Sciomyzidae – marsh flies, snail-killing flies (including Huttoninidae, Phaeomyiidae, Tetanoceridae)


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.


Tipuloidea is a superfamily of flies containing the living families Cylindrotomidae, Limoniidae, Pediciidae and Tipulidae, and the extinct families Architipulidae and Eolimnobiidae.At least 15,300 species of crane flies have been described, most of them (75%) by the specialist Charles Paul Alexander.


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.
