The Ulidiidae or picture-winged flies are a large and diverse cosmopolitan family of flies (Diptera), and as in related families, most species are herbivorous or detritivorous. They are often known as picture-winged flies, along with members of other families in the superfamily Tephritoidea that have patterns of bands or spots on the wings. Some species share with the Tephritidae an unusual elongated posteroapical projection of the anal cell in the wing, but can be differentiated by the smoothly curving subcostal vein. Two species, Tetanops myopaeformis and Euxesta stigmatias, are agricultural pests.
Chrysopilus is common, worldwide genus of predatory snipe flies. There are approximately 300 species in the genus, including fossil members that are sometimes found in amber.
Rhagio is a worldwide genus of predatory snipe flies. Several species in this genus are referred to as downlooker or down-looker flies because they sometimes perch on tree trunks in a head-down position. There are approximately 170 species. They can be distinguished from other rhagionids by the open anal cell on the wings and the lack of a kidney-shaped arista.
Superfamily Tabanoidea are insects in the order Diptera.
Xylota is a Holarctic genus of hoverflies similar in structure to the related genera Chalcosyrphus and Brachypalpoides. As the larvae are saprophytic they're usually found in rotting wood. The adult flies are generally associated with woodland and woodland edges and can often be seen running over the upper sides of leaves. Unlike other syrphids the adults of many species rarely visit flowers preferring instead to gather pollen from leaf surfaces. There are over 100 described species of which 12 can be found in Europe. Seven species have been recorded in Britain. Identification of species has been difficult and identifiction by photographs is risky.
Pangonius is a genus within the horse-fly family (Tabanidae), often misspelled as Pangonia; Latreille originally published the name as Pangonius in 1802, emending it in 1804 to Pangonia, but the emendation is not valid under the International Code of Zoological Nomenclature. Some species that were earlier placed in this genus are now in the genus Philoliche.
Urophora is a genus of tephritid or fruit flies in the family Tephritidae.
Tropidia is a genus hoverflies, from the family Syrphidae, in the order Diptera.
Scaptia is a genus of Horse-fly in the tribe Scionini.
The Milesiini is a large and diverse tribe of hoverflies. They mimic wasps or hornets.
Dexiinae is a subfamily of flies in the family Tachinidae.
Dexiini is a tribe of flies in the family Tachinidae.
Otitinae is the name of a subfamily of flies in the family Ulidiidae. It was formerly the Otitidae. Like the Ulidiinae, most species are herbivorous or saprophagous. Most species share with the Tephritidae an unusual elongated projection of the anal cell in the wing, but can be differentiated by the smoothly curving subcostal vein. Most are dull gray to shiny brown or black flies with vein R1 setulose or, in a few cases, bare.
Arthropeas is a genus of flies in the family Xylophagidae.
Dialysis is a genus of flies in the family Xylophagidae.
