Length 10 mm. Male.
"Face chestnut brown, concave below the antennae with a prominent rounded tubercle about the middle, below which it is slightly produced to the not prominent oral margin ; side margins well defined, as in Chilosia, the facial slopes with fine whitish pollen, the side margins with sparse whitish pile ; cheeks and frontal triangle shining, concolorous with the face ; vertical triangle brown, the sides of the triangle about equal, with brown pile ; occiput shining chestnut, with whitish pile below and brownish above. " [1]
" shining blueblack, the dorsum with yellow pile, which is intermixed with black on the middle, and black pile on the borders; pleurae yellowish brown, with yel- lowish pile, the pile black above. Scutellum concolorous with dorsum, with slightly longer black pile. " [1] "Abdomen narrow, and gradually narrowing after the second segment, in color shining blue-black, the posterior margins of the second and third segments a little more blackish on the median two-thirds ; hypopygium black. Pile of abdomen yellowish on basal angles, becoming white en the hypopygium, and black on the ends of the second and third segments." "Legs chestnut brown.

Toxomerus geminatus (Say,1823) the Eastern Calligrapher, is a common species of syrphid fly observed in the eastern and central United States and Canada.(see map) Syrphid flies are also known as Hover Flies or Flower Flies because the adults are frequently found hovering around flowers from which they feed on nectar and pollen. Adults are 6.1–7.6 mm (0.24–0.30 in) long. The larvae are predators of a variety of aphids and mites.
Toxomerus politus, commonly known as the maize calligrapher, is a species of hoverfly. It is known from North, Central and South America. Although little is known about the early stages of this species, associations with corn have been noted. The adults and likely the larvae feed on the pollen of the corn plants.
Brachyopa flavescens, The Yellow Sapeater, is a fairly common 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.flavescens larvae have not been described.
Blera nigra , the golden-haired wood fly, is a fairly common species of syrphid fly first officially described by Williston in 1887 Hoverflies get their name 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.
Helophilus fasciatus, the narrow-headed marsh fly, is an abundant species of syrphid fly observed throughout the United States and 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. The larvae of this genus are associated with wet decaying organic material, particularly accumulations of decaying vegetation in ponds and mud and farmyard manure or silage. The adults of this species lays eggs on vegetation overhanging the water. The larvae hatch and drop into the water.
Eristalis transversa, the transverse banded drone fly, is a common species of syrphid fly first officially described by Wiedemann in 1830. 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 rat-tailed type but larvae of this specific species has not been reported.
Blera badia, the Common Wood Fly, is a common species of syrphid fly first officially described by Walker in 1849. 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.
Helophilus lapponicus, the Yellow-margined Marsh Fly, is a common species of syrphid fly observed across northern North America, northern Europe, Greenland and Siberia. 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. Though common the larvae of this species are not known but the larvae of other species in this genus are associated with wet decaying organic material, particularly accumulations of decaying vegetation in ponds and mud and are a so called rat-tailed type.
Arctosyrphus willingii, the northern longbeak, is a species of rat-tail maggot fly in the family Syrphidae. This species was formerly a member of the genus Lejops.
Hadromyia aepalius, the Sterling Quicksilver, is a rare species of syrphid fly found in eastern 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.
Blera pictipes, the painted wood fly, is a rare species of syrphid fly first officially described by Bigot in 1883. 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.

The larvae are of the rat-tailed type feeding on exuding sap or in the rot holes of trees.
Blera robusta, the greenish wood fly, is a rare species of syrphid fly first officially described by Curran in 1922.

The larvae are of the rat-tailed type, feeding on exuding sap or in the rot holes of trees.
Blera analis, the orange-tailed wood fly, is an uncommon species of syrphid fly. It was officially described by Macquart, 1842. Hoverflies get their names from their 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.
Blera scitula, the western wood fly, is an uncommon species of syrphid fly first officially described by Williston in 1882.
