Pterallastes is a genus of bee-mimicking hoverflies. So far the genus contains only four species, one in North America, one from Japan, and two from China. [6] [7] [8]
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.
Spilomyia is a genus of hoverflies. Many species in the genus show Batesian mimicry of wasp models, including black and yellow patterns and modified antenna shape.
Procecidochares is a genus of tephritid or fruit flies in the family Tephritidae.
Temnostoma is a genus of hoverflies. The larvae of some species feed on the wood of deciduous trees.
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.
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.
Tropidia is a genus hoverflies, from the family Syrphidae, in the order Diptera.
The Milesiini is a large and diverse tribe of hoverflies. They mimic wasps or hornets.
Teuchocnemus is a genus of North American flower flies.
Chrysogaster antitheus , the Short-haired Wrinkle Fly, is a fairly common species of syrphid fly found in North America. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae in this genus are aquatic rat-tailed larvae.
Pterallastes thoracicus , the Goldenback Fly, is an uncommon species of syrphid fly observed across central and eastern areas of the United States. Hoverflies can remain nearly motionless in flight while many are mimics of bees. The adults are also known as flower flies for they are commonly found on flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae are unknown.
Lejota is a genus of syrphid flies in the family Syrphidae.
Tropidia mamillata is a species of hoverfly in the family Syrphidae.
Pterallastes unicolor is a species of hoverfly in the family Syrphidae.
Pterallastes bomboides is a species of hoverfly in the family Syrphidae.
Sphegina infuscata is a species of hoverfly in the family Syrphidae.
Sphegina rufiventris, the Black-horned Pufftail, is a common species of syrphid fly observed in the northestern United States. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies for they are commonly found on flowers, from which they get both energy-giving nectar and protein-rich pollen. Larvae are found in accumulations of decaying sap under bark, usually in wet situations such as damp, shaded woodland and in partially submerged wood in streams and pools.
Total of 245 species either found or highly expected to be found in New York.
