Paratropidia is a subgenus of hoverflies from the family Syrphidae, in the order Diptera. [3]
Hover flies of the genus Microdon are unusual among the Diptera. Like other members of the subfamily, they are myrmecophiles, meaning they inhabit the nests of ants.
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.
Ceriana is a genus of hoverfly. All species are wasp mimics.
Chalcosyrphus is a genus of hoverflies in the subfamily Eristalinae. Many species exhibit some degree of mimicry of various sawflies and other hymenopterans and are often brightly coloured or metallic in hue. The adults are similar in structure and behavior to the related genus Xylota but differ in larval morphology. They can be found throughout Europe, Asia, and North America and seem to prefer damper, boggy habitats. The larvae are saproxylic feeders in rotten wood in these habitats.
Sphegina is a genus of small, slender hoverflies. They are widespread throughout Eurasia and North America. In flight they seem to have long hind legs which they often carry hanging down, making them resemble sphecid or ichneumonid wasps. Adult Sphegina are usually found in damp and shady habitats close to water in forested areas, and several species can often be found together. They often feed on white and yellow flowers of Apiaceae, Ranunculaceae, Asteraceae, and Rosaceae like Crataegus, Sorbus, and Sorbaria. Larvae nest in the sap of living and dead trees or in decaying cambium under tree bark lying in water or other damp conditions. The larvae of some species have been discovered in the tunnels of other xylophagous insects.
Mixogaster is a genus of hoverflies native to North America and South America, with 21 known species. Mixogaster is distinct by lacking an appendix on vein R4+5, having a reduced and bare metasternum, an unarmed scutellum, and usually an appendix on vein M extending in cell R4+5. Larvae are found in ant nests.
Monoceromyia is a genus of hoverfly. Species in the genus are found in the Afrotropical, Australasian, Neotropical and Oriental regions. They are mimics of wasps and the genus is distinguished by the metapleura being widely separate behind the hind coxae. The elongated frontal base of the antenna is at least as long as the basal segment of the antenna and the second abdominal tergum is longer than wide and constricted.
The Milesiini is a large and diverse tribe of hoverflies. They mimic wasps or hornets.
Milesia is a genus of very large hoverflies, which mimic social wasps. For example, the European species Milesia crabroniformis is a convincing mimic of the hornet species Vespa crabro. Milesia are predominantly Palaeotropical in distribution almost entirely Oriental.
Graptomyza is a genus of hoverflies.
Orthoprosopa is a genus of hoverflies from the family Syrphidae, in the order Diptera.
Orthoprosopa grisea is a species of hoverfly in the family Syrphidae.
Orthoprosopa xylotaeformis is a species of hoverfly in the family Syrphidae.
Orthoprosopa alex is a species of hoverfly in the family Syrphidae.
Orthoprosopa bilineata is a species of hoverfly in the family Syrphidae.
Orthoprosopa margarita is a species of hoverfly in the family Syrphidae.
Orthoprosopa multicolor is a species of hoverfly in the family Syrphidae.
Orthoprosopa pacifica is a species of hoverfly in the family Syrphidae.
Sterphus is a genus of hoverflies.
