Parhelophilus is a genus of hoverflies. [1] [2] [3] They are slightly smaller than flies of the genus Helophilus, and have a Holarctic distribution. [4]
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.
Cheilosia is a genus of hoverfly. Most Cheilosia are black or largely un-coloured, lacking the bright colours and patterns of many hoverfly species. It is one of the most species diverse genera of hoverflies. The biology of many species is little understood, but where known, the larvae of Cheilosia species feed in the stems of plants or in fungi.
Eumerus is a genus of hoverflies, within the tribe Eumerini.
Temnostoma is a genus of hoverflies. The larvae of some species feed on the wood of deciduous trees.
Platycheirus is a large genus of hoverflies. They are also called sedgesitters.
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.
Xanthandrus is a small genus of hoverflies.
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.
Doros is a genus of hoverflies. They are large slender flies, that mimic solitary wasp in slow flight. They have very limited flight period.
Callicera is a Holarctic genus of hoverflies
Ferdinandea is a genus of syrphid flies or hoverflies in the family Syrphidae. There are about 16 described species in Ferdinandea.
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.
Orthonevra is a genus of fly in the syrphidae family with at least 59 species identified so far. They are worldwide in distribution but concentrated in the Eastern North America and Europe.Orthonevra are commonly called Mucksuckers after the larvae which have been found in organic rich mud, i.e. muck. This genus belongs to the tribe Brachyopini that includes the prominent genera Melanogaster, Brachyopa, Neoascia and Sphegina. Orthonevra have black heads with blue to purple reflections. Many species have distinctive eye stripes. The antennae are somewhat elongate. The frons is wrinkled with silvery spots at sides of antennae. The thorax with small punctures dorsally and in several species the body is covered with scale-like pile. Wingd vein M1 curves away from the wing tip.(see images)
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.
Pipiza is a genus Hoverflies, from the family Syrphidae, in the order Diptera. Most are dark hoverflies.
Trichopsomyia is a genus of Hoverflies, from the family Syrphidae, in the order Diptera.
Total of 245 species either found or highly expected to be found in New York.
