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.


Agromyza is a genus of flies belonging to the family Agromyzidae. The adults of these flies can be recognised by the presence of stridulatory files on the first two abdominal tergites in both males and females. Another useful identifying feature is the halteres which are usually white or yellow, although they are darker in a few tropical species.

The larvae of these flies are mostly leaf miners on a wide range of plants, although a few form galls. Some are economic pests.


Anthomyza is a genus of flies in the family Anthomyzidae. It is found in the Palearctic.


The Anthomyzidae are small, slender, yellow to black flies with narrow and elongated wings, which may have distinct markings. Some species have greatly reduced wings. Fewer than 100 species are known, mostly from Europe. Although they occur in all major regions, they seem to be most varied in the Holarctic region.

Around 20 diverse genera have been placed in the family. Two, Teratomyza and Teratoptera, are now in the Teratomyzidae, and Cyamops and Stenomicra are in the Stenomicridae. Melanthomyza Malloch from Chile should probably not be retained in the family. The remaining genera are very similar to one another.


Asteiidae is a small but widespread family of acalyptrate flies or Diptera. About 130 species in 10 genera have been described worldwide. They are rarely collected.


Aulacigastridae is a very small family of flies known as sap flies. The family Stenomicridae used to be included within this family, but was moved by Papp in 1984. They are found in all the Ecoregions.


Calycomyza is a genus of leaf miner flies in the family Agromyzidae. There are at least 30 described species in Calycomyza.


Cerodontha is a genus of leaf miner flies in the family Agromyzidae. There are at least 280 described species in Cerodontha.


Cyamops is a genus of flies.


Liriomyza is a genus of leaf miner flies in the family Agromyzidae. There are at least 410 described species in Liriomyza.

Liriomyza trifolii

Liriomyza trifolii, known generally as the American serpentine leafminer or celery leafminer, is a species of leaf miner fly in the family Agromyzidae.


The Brachyceran infraorder Muscomorpha is a large and diverse group of flies, containing the bulk of the Brachycera, and, most of the known flies. It includes a number of the most familiar flies, such as the housefly, the fruit fly, and the blow fly. The antennae are short, usually three-segmented, with a dorsal arista. Their bodies are often highly setose, and the pattern of setae is often taxonomically important.

The larvae of muscomorphs (in the sense the name is used here; see below) have reduced head capsules, and the pupae are formed inside the exoskeleton of the last larval instar; exit from this puparium is by a circular line of weakness, and this pupal type is called "cyclorrhaphous"; this feature gives this group of flies their traditional name, Cyclorrhapha.


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.


Opomyza is a genus of acalyptrate flies.


Opomyzidae is a family of acalyptrate Diptera. They are generally small, slender, yellow, brown or black coloured flies. The larval food plants are grasses, including cereal crops, the adults are mainly found in open habitats. Some species being agricultural pests.


Periscelididae is a family of flies.


Phytoliriomyza is a genus of leaf miner flies in the family Agromyzidae. There are at least 20 described species in Phytoliriomyza.


Phytomyza is a genus of leaf miner flies in the family Agromyzidae. At least 170 described species are placed in Phytomyza.


Sobarocephala is a genus of flies in the family Clusiidae. There are at least 100 described species in Sobarocephala.
