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.
Tropidia is a genus hoverflies, from the family Syrphidae, in the order Diptera.
Neoascia metallica, the Double-banded Fen Fly, is a common species of syrphid fly observed across 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 are aquatic.

Chalcosyrphus (Xylotomima) piger, the short-haired leafwalker, is an uncommon species of syrphid fly found throughout North America and Europe. 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 have been identified from sappy hollows from Larix and Pinus.
Milesia virginiensis, known generally as the yellowjacket hover fly or Virginia flower fly, is a species of hoverfly in the family Syrphidae.
Tropidia coloradensis is a species of hoverfly in the family Syrphidae.
Blera notata , the Ornate Wood Fly, is a rare species of syrphid fly first officially described by Weidemann in 1830. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults, 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.
Chalcosyrphus satanicus is a species of hoverfly in the family Syrphidae.
Xylota annulifera ,, the Longspine Leafwalker , is an uncommon species of syrphid fly observed across Canada and in the eastern United States. 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 7.5–11.8 mm (0.30–0.46 in) long, black with yellow abdominal spots. The larvae of this genus live under bark in sap runs.

Sphegina albipes is a species of hoverfly in the family Syrphidae.
Brachyopa cinereovittata, the Grey-striped Sapeater, is a rare species of syrphid fly. It has been observed in northwestern 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.cinereovittata larvae have not been described.
Microdon cothurnatus , the orange-legged ant fly, is a species of syrphid fly observed across the Northern 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 except Microdon species are seldom observed around flowers. Larvae have been found in several species of ant.
