Paragus is a genus of hoverflies.
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.
Platycheirus is a large genus of hoverflies. They are also called sedgesitters.
Parasyrphus is a genus of hoverflies.
Allograpta is a very large and diverse genus of hoverflies present throughout the world except most of the palearctic region. The adults are brightly coloured flower pollinators and most larvae have a predatory feeding mode involving soft-bodied sternorrhynchans. Certain species have diverged from this and their larvae have been found to be leaf-miners, stem-borers or pollen-feeders.
Toxomerus is a very large genus of hoverflies. They are found in many parts of North and South America. Most larvae are predators on soft bodied insects, though a few species have been shown to feed on pollen. Adults feed on the pollen of a wide range of flowers.
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.
Pipiza is a genus Hoverflies, from the family Syrphidae, in the order Diptera. Most are dark hoverflies.
The Syrphini are a tribe of hoverflies.
Rohdendorfia is a genus of hoverflies.
Spazigaster is a genus of hoverflies. The genus was first recorded in 1843 in Iran.
Syrphocheilosia is a genus of hoverflies.
Talahua is a genus of hoverflies.
Tuberculanostoma is a genus of hoverflies.
Pyrophaena is a subgenus of the hoverfly genus Platycheirus distinctive enough to sometimes treated as a separate genus in its own right. Indeed a recent study of the phylogeny of the subfamily Syrphinae found it to be closer to other certain other genera – Rohdendorfia, Syrphocheilosia and Spazigaster. Since only a few species were sampled the true systematic structure must await a more thorough survey of Platycheirus and related genera.
Ocyptamus is a large and diverse genus of over 200 species of hoverfly mostly found in the Neotropical region. It is likely that many of these species will be discovered to be synonyms though many others await description.
Parasyrphus nigritarsis is a species of hoverfly, from the family Syrphidae, in the order Diptera. It is known from northern Europe and North America, and has been considered to be a rare species in parts of its range. Adults visit flowers as a source of nutrition, and females lay their eggs on clutches of eggs of leaf beetles. When the Parasyrphus larvae hatch, they first consume leaf beetle eggs and then consume immature beetles until they reach the pupal stage. This species is related to hoverflies that prey on aphids as larvae, and has been investigated in studies of chemical ecology and food web ecology.
