Syrphocheilosia is a genus of hoverflies.

Hover flies, also called flower flies or syrphid flies, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects.
The subfamily Microdontinae contains slightly more than 400 species of hoverflies and, while diverse, these species share several characteristics by which they differ from other syrphids. The Microdontinae are myrmecophiles, meaning they live in the nests of ants. Larval Microdontinae are scavengers or predators in ant nests, and, in contrast to other syrphid larvae, have no readily apparent body segmentation. Some species also do not exhibit the typical adult flower-visiting behaviour of other hoverflies, but instead remain near their larval host colonies.
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.
Syritta pipiens, sometimes called the thick-legged hoverfly, is one of the most common species in the insect family Syrphidae. This fly originates from Europe and is currently distributed across Eurasia and North America. They are fast and nimble fliers, and their larvae are found in wet, rotting organic matter such as garden compost, manure, and silage. The species is also commonly found in human-created environments such as most farmland, gardens, and urban parks, wherever there are flowers. This species is an important part of its native ecosystem as adult Syritta pipiens flies are critical pollinators for a variety of flowering plants and the species supports parasitism by various parasitic wasp species. Thus, they play an important role in environmental functionality, and can serve as bio-indicators, in which their abundance can reflect the health of the environment. They can also serve as a biological control agent against pests such as lettuce aphids.
Eristalinus is a genus of hoverfly. Most species have very distinctive eye marking in the form of spots or banding, though these features may fade on some preserved specimens. Most are stout flies, and are nimble flyers, even compared to other hoverfly species.
Eupeodes luniger is a common species of hoverfly.
Cheilosia albipila is a European and Palearctic species of hoverfly. Like most Cheilosia it is black, and because of this may often be overlooked as a hoverfly. It is little recorded but probably widespread and common and maybe overlooked because adult flight periods are early in the year, before many hoverfly recorders are active.
Merodon equestris is a Holarctic species of hoverfly. Like many other hoverflies it displays a colouration pattern similar to a stinging insect as an evolutionary defense mechanism. Other syrphid bee mimics are Mallota, Arctophila, Criorhina, Pocota and Brachypalpus. Merodon species are distinguished from these by the very strong hind femora, which bear a large triangular projection on the underside near the tip. It flies in low vegetation while the other bumblebee mimics prefer higher vegetation layers.
Blera is a genus of hoverflies. It is primarily a North American genus, though there are 3 species from Europe.
Chalcosyrphus nemorum is a Palearctic and Nearctic species of hoverfly.
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, North America and South 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.
Callicera is a Holarctic genus of hoverflies
Brachyopa is a Holarctic genus of hoverflies whose grey and brown colouration is unusual for this family and these flies can easily be overlooked amongst members of other fly families. The larvae can be found under the bark of dead branches and trees in decaying sap.
Myolepta is a cosmopolitan genus of hoverflies most closely related to the genus Lepidomyia
Neoascia is a genus of hoverflies.
Lejops is a genus of hoverflies. The majority of the species are found in the Americas and Australia, with the exception of Lejops vittatus which is found in Europe and Asia.
Sericomyia is a genus of large Hoverflies, from the family Syrphidae, in the order Diptera.
The Milesiini is a large and diverse tribe of hoverflies. They mimic wasps or hornets.
