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.
'Brachyopa notata , the Black-banded Sapeater , is a rare species of syrphid fly. It has been observed in Northeastern 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. Larvae for this genus are of the rat-tailed type. B.notata larvae have not been described.

The larvae burrow in moist decayed wood.
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.

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.
'Spilomyia intertupta , the Interrupted Hornet Fly, is an uncommon species of syrphid fly first officially described by Williston, 1882. This species is found in Western North America, along the California coast. 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 known as the short-tailed larva, suited for moist areas such as rot holes of trees.
Brachypalpus femorata, the Orange Catkint, is an uncommon species of syrphid fly first officially described by Williston in 1882. 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.
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.
Lejota aerea , the Golden Trunksitter , is an uncommon species of syrphid fly observed in eastern 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 of this genus are found in decaying tree roots.
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.
Sphegina (Sphegina) keeniana, the Peg-legged Pufftail, is a fairly common species of syrphid fly observed in Eastern 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 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.
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.
Orthonevra nigrovittata (Loew, 1876), the black-lined mucksucker, is a rare species of syrphid fly. It has been observed in California. 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. O. nigrovittata larvae have not been described.
Anasimyia distincta, the short-spurred swamp fly, 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. Larvae of this genus are of the rat-tailed type living in aquatic environments.
