Helophilus are a diverse genus of moderate to large hoverflies, that appear somewhat bee-like. Larvae filter-feed in organic rich water. All Helophilus adults have a distinctive lengthwise striped thorax and a transverse striped abdomen.
Platycheirus clypeatus is a species of hoverfly. It is found across the Palearctic and in the Nearctic. The larvae feed on aphids. Adults are usually found on the edges of woodland or scrub, heath or along hedgerows where they visit a wide range of flowers.
Doros is a genus of hoverflies. They are large slender flies, that mimic solitary wasp in slow flight. They have very limited flight period.
Platycheirus albimanus is a common widespread species of hoverfly. A holarctic species its range includes Greenland, Iceland, Britain, mainland Europe, Russia, across Siberia to the pacific coast, the Philippines, Alaska, western Canada and United States.
Platycheirus manicatus is a species of hoverfly. It is found across the Palearctic and in Alaska.
Callicera is a Holarctic genus of hoverflies
Hammerschmidtia is a Holarctic genus of hoverflies whose larvae live in sap under the bark of freshly fallen trees.
Lejogaster is a genus of small, shiny, metallic hoverflies.
Myolepta is a cosmopolitan genus of hoverflies most closely related to the genus Lepidomyia
Neoascia is a genus of small black and yellow or mostly black flies with a narrow abdomen near the thorax. They occur mainly in damp places among low herbage. The larva of Neosascia are flattened without oral hooks and a have a short posterior spiracular process or "tail" rat-tailed that is saprophagous. In 1925 Curran reviewed the genus Neoascia. In this work a key is provided and ten species are described including four new species some of which have later been determined to be synonyms.
Riponnensia is a genus of hoverflies.
Anasimyia is a genus of wetland hoverflies with aquatic larvae. The genus was formerly regarded as a subgenus of the similar Lejops, and recently elevated to genus.
Parhelophilus is a genus of hoverflies. They are slightly smaller than flies of the genus Helophilus, and have a Holarctic distribution.
Pipiza is a genus Hoverflies, from the family Syrphidae, in the order Diptera. Most are dark hoverflies.
Pipizella is a genus of Hoverflies, from the family Syrphidae, in the order Diptera.
Sercomyia are large flies with species that are bee mimics both short pile and long pile. Sericomyiine flower flies are common in boreal forests across the Holarctic region and southward at higher elevations into the Oriental and Neotropical regions. Sericomyia species have larvae of the rat-tailed maggot type, often found in ponds rich in decomposing vegetation where they filter out microorganisms as their food
Brachypalpus is a genus of hoverflies, from the family Syrphidae, in the order Diptera. The head is triangular and produced well forwards and somewhat downwards. The thorax and abdomen with pile often rather long. The hind femur is swollen and with an obtuse spur apically and ventrally. The hind trochanters of male is spurred.
The larvae are of the rat-tailed type feeding on decaying sap under tree bark. Larvae live in decaying trees and logs. Larva and pupa have been described by Malloch.
Portevinia maculata, also known as the ramsons hoverfly, is a European species of hoverfly. The adults can be found around Allium species when the plants are in flower (May–June). The larvae tunnel through and overwinter in the bulbs of this plant.
Platycheirus nielseni is a Holarctic species of hoverfly.
Eumerus tuberculatus, the lesser bulb fly is a species of hoverfly from the family Syrphidae, in the order Diptera. It is a pest that destroys the bulbs of Narcissus.
