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 very fragile small insects usually only 2–3 mm (0.079–0.118 in) in length; many are less than 1 mm (0.039 in) long. They are characterised by hairy wings, unusual in the order Diptera, and have long antennae. Some Cecidomyiids are also known for the strange phenomenon of paedogenesis in which the larval stage reproduces without maturing first. In some species, the daughter larvae consume the mother, while in others, reproduction occurs later on in the egg or pupa.
The Cecidomyiinae are a subfamily of flies often called gall midges or gall gnats. This subfamily is best known for its members that induce galls on plants, but there are also many species that are fungivorous, parasitoids, or predacious as maggots.
Anabremia inquilina is a gall midge and a member of the genus Anabremia. This species was first described from Italy in 1965. It is an inquiline of another gall midge - Jaapiella medicaginis - which makes galls on Medicago species.
Schismatodiplosis is genus of flies in the family of gall midges Cecidomyiidae.
Rabdophaga strobilina is a gall midge and inquiline of Rabdophaga rosaria and Rabdophaga terminalis; also gall midges. It was first described by Johann Jacob Bremi-Wolf in 1847.
Asphondylia is a cosmopolitan genus of gall midges in the family Cecidomyiidae. All species in this genus induce galls on plants, especially on flowers and flower buds. There are over 300 described species in Asphondylia, with many more likely to be discovered and described, especially in the southern hemisphere.
Rhopalomyia is a genus of gall midges, insects in the family Cecidomyiidae. There are at least 267 described species in Rhopalomyia. Most species in this genus induce galls on plants in the Asteraceae. This genus has a cosmopolitan distribution. Rhopalomyia was first established by Ewald Heinrich Rübsaamen in 1892.
Asphondylia betheli is a species of gall midge in the family Cecidomyiidae. This midge is widespread in the southwestern United States. The larvae of this species induce galls on in the fruit of Opuntia cacti.
Catotricha is a genus of midges in the family Cecidomyiidae. The five described species in Catotricha are found in the holarctic region. This genus was established by British entomologist Frederick Wallace Edwards in 1938.
Ampelomyia vitiscoryloides, the Grape Filbert Gall Midge, is a species of gall midge in the family Cecidomyiidae. It induces galls on grape plants and is widespread in eastern North America. It was first described by Alpheus Spring Packard in 1869.
Micromyinae is a subfamily of wood midges, insects in the family Cecidomyiidae. Its members were formerly included in subfamily Lestremiinae. There are at least 55 genera and more than 650 described species in Micromyinae. All species in this subfamily are mycophageous.
Asphondylia solidaginis is a species of gall midge (Cecidomyiidae) that induces galls on goldenrods in North America where it is widespread. It was first described by William Beutenmuller in 1907.
Ampelomyia is a genus of gall midges in the tribe Asphondyliini. It consists of the following four species, all of which form galls on grape plants:
Raymond J. Gagné is an American entomologist whose work focuses on gall midges.
Wheeleriola is a genus of midges in the family Cecidomyiidae. The one described species in this genus - Wheeleriola perplexa - is known only from New Zeland.
Anodontoceras is a genus of wood midges in the family Cecidomyiidae. There are three described species. The genus was established by Japanese entomologist Junichi Yukawa in 1967.
Berestella is a genus of wood midges in the family Cecidomyiidae. The only described species - Berestella insuperabilis - is only known from Rovno amber from the Late Eocene. The genus was established in 2007 and named for Ukrainian entomologist Zoya L. Berest.
Corporesana is a genus of wood midges in the family Cecidomyiidae. The one described species - Corporesana khatanga - is only known from Taymyr amber from the Late Cretaceous.
Cretomycophila is a genus of wood midges in the family Cecidomyiidae. The one described species - Cretomycophila ekaterinae - is only known from Taymyr amber from the Late Cretaceous.
Cretoperomyia is a genus of wood midges in the family Cecidomyiidae. The one described species - Cretoperomyia dmitrii - is only known from Taymyr amber from the Late Cretaceous.
