Eristalis is a large genus of hoverflies, family Syrphidae, in the order Diptera. Several species are known as drone flies because they bear a resemblance to honeybee drones.
Blera is primarily a North American genus, though there are 3 species from Europe. The genus is characterized by the following characters:
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.
Teuchocnemus is a genus of North American flower flies.
Sphecomyia brevicornis is a species of syrphid fly in the family Syrphidae.
Sphecomyia is a genus of hoverfly in the family Syrphidae. There are about 16 described species in Sphecomyia.
Eristalis dimidiata, the black-shouldered drone fly, is a species of hoverfly native to much of Canada and the eastern and northern United States. It flies year-round in southern areas and from late March to mid-November further north. It is one of the earliest hoverflies to fly in the spring, and as such likely overwinters as an adult. It lives primarily in forests.
Brachyopa vacua , the Yellow-spotted Sapeater, is a rare, species of syrphid fly. It has been observed in Canada, Alaska and northern United States. 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. Larvae for this genus are of the rat-tailed type. B.vacua larvae were collected from the juice of decaying fungi under dead bark.
Temnostoma venustum , the Black-banded Falsehorn , is a rare species of syrphid fly observed in the northeastern United States and adjacent Canada. 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. Temnostoma adults are strong wasp mimics The larvae burrow in moist decayed wood.
Blera armillata, the orange-faced wood fly, is an uncommon species of syrphid fly first officially described by Osten Sacken in 1875. 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 are of the rat-tailed type, feeding on exuding sap or in the rot holes of trees.
Brachypalpus cyanella , the Longnose Catkin, is a rare species of syrphid fly first officially described by Osten Sacken in 1877 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 are of the rat-tailed type feeding on decaying sap under tree bark.
Chalcosyrphus (Xylotomima) vecors , the Orange-hipped Leafwalker, is an uncommon species of syrphid fly observed throughout North America. Hoverflies can remain nearly motionless 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.
Eristalis hirta, the black-footed drone fly, is a common Western North American species of syrphid fly, first officially described by Loew in 1866. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies as they are commonly found on and around flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae are aquatic filter-feeders of the rat-tailed type.
Syrphus rectus, the yellow-legged flower fly, is a species of fly in the family Syrphidae, the hover flies. Syrphus rectus is a common fly in the eastern United States and southeastern Canada. Like many hoverflies, it has strongly contrasting black and yellow bands on the abdomen.
Tropidia calcarata, the Lily-loving Thickleg Fly, is a rare species of syrphid fly observed from northeastern North America. 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. The larvae have been found on the rotting roots of an aquatic lily.
Spilomyia ephippium is a species of Hoverfly in the family Syrphidae.
Brachyopa media ( Williston, 1882), is a rare species of syrphid fly. It has been observed in the Northeastern United States. 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. Larvae for this genus are of the rat-tailed type. B.media larvae have not been described.
Megasyrphus laxus , the black-legged gossamer fly, is an uncommon species of syrphid fly observed throughout North America. 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 unknown.
Total of 245 species either found or highly expected to be found in New York.
