Total of 245 species either found or highly expected to be found in New York.
Hammerschmidtia is a Holarctic Genus of hoverflies. The larvae are found in sap under the bark of downed trees. They appear quite unlike other syrphids, having drab colors and numerous bristles but on closer inspection they do have the general indicators of syrphids in a spurious vein.
Three species of Myolepta occur in New York. Keys and descriptions of this species was made by Fluke and Weems in 1956. Larvae are described by Rotheray
Neoascia <small>(Williston, 1886)</small> Fen Flies These are very small (3.5âÂÂ5 mm) black and yellow or metallic green flies with a narrow abdomen near the thorax. They occur mainly in damp places around plants. . Neoascia larvae have been recovered from wet manure in farmyards, and decaying vegetation at the edges of ponds. In 1925 Curran reviewed the Genus Neoascia
Four species Orthonevra <small>(Macquart, 1829)</small> of these small dark metallic flies are found in New York. Sedman divided this genus into two groups, the pictipennis group of which N.Y. has O. pictipennis, O. Weemsi and O. pulchella and the Bellula group with O. nitida being found in N.Y. This genus is one of the few where the eyes are ornamented with either horizontal medial lines or meandering lines across the eye. Keys and descriptions have been provided by Sedman.
These are distinctive small flies with a thin elongate abdomen and enlarged hind femur often with spines and or teeth. The larvae are found under bark in water soaked areas. Rotheray has described European species and habitats as well as a key to larvae including sphegina and other syrphid genera. Keys to adult American species was provided by Coovert. New York species can also be found southward especially in the Appalachian Mountains and also north to the New England States.<br> There are various keys online, Covert 1977 Hull, 1935 and Malloch, 1922

Only one species of this tribe is found in New york in the genus Callicera <small>(Panzer, 1809)</small>.
Ceriana<small>(Rafinesque, 1815)</small> has but one species in New York.
Sphiximorpha <small>(Rondani, 1850)</small> is represented by a single rare species in New York.
New York has an prevalence of Eristalids many of which are striking in color and exhibit mimicry to the bees. The larvae are of the rat-tailed type. Eristalis along with many sister species has the r<small>4+5</small> vein making a distinct loop towards the rear of the wing.
Large flies that strongly resemble bumblebees. The larvae of, M. cimhiciformis (Fallen) and M. posticata (Fabricius) develop in detritus-containing rot pockets, usually wet tree holes in upright deciduous trees.
This tribe has only one genus
This tribe contains 17 genera with 56 species found in New York
Cynorhinella <small>(Curran, 1922)</small> is a rare genus in New York with a single species.
Hadromyia <small>(Williston, 1882)</small> a single species in New York
Lejota (Róndani, 1857) has two uncommon species in New York.
Milesia <small>(Latreille, 1804)</small> represented by a single, vivid species.
Pterallastes <small>(Loew, 1863)</small>
Somula <small>(Macquart, 1847)</small> has only two species worldwide, with one in New York.
Sphecomyia <small>Latreille, 1829</small> is a genus of wasp mimics with one species found in New York.
Many species in Spilomyia are wasp mimics with black and yellow patterns and using the black front legs to imitate the wasp antennae. The eyes on Spilomyia species are a distinctive characteristic which usually display vertical, and irregular stripes or blotches.
Teuchocnemis <small>(Osten-Sacken, 1876)</small> species are more commonly found south of New York.
This tribe contains 5 genera and 8 species found in New York State
This is a very large genus of little black flies with larvae feeding on plants or fungi.
Ferdinandea <small>(Róndani, 1844)</small> has a single species in New York with a second species, Ferdinandea croesus, reported but the identity is not confirmed.
Pelecocera <small>(Meigen, 1822)</small> only reported from Long Island but may be more common as the small size and habit of staying in low lying flowers may make this fly under-reported.
Rhingia<small>(Scopoli, 1763)</small> has only one species in North America.
Copestylum <small>(Macquart, 1846)</small> due to the larval habit of living in Bromeliads only one species is found in New York.
Volucella <small>(Geoffroy, 1762)</small> has two species that represent some of the best bumblebee mimics in New York. The larvae of most species live in nests of bumblebees and social wasps, where they are detritivores and larval predators.
This is the newest subfamily and the smallest in New York. The adult fly looks very much like the flies in Eristalinae while the larvae are predators much like the subfamily Syrphinae. The DNA evidence has been evaluated and concluded that Pipizinae are a sister subfamily to these subfamilies.
Pipiza <small>(Fallén, 1810)</small> is a genus of small nearly all black flies sometimes with yellow abdominal spots. The larvae, when known, feed upon gall making or leaf rolling aphids. Pipizini. The larvae of Pipiza species (fig. 257) seem to prefer aphids which secrete a waxy flocculence, e.g. woolly aphid (Eriosoma). Pipizella larvae confine their attention to subterranean aphids feeding on the roots of plants.
Trichopsomyia <small>(Williston, 1888)</small> is another genus of small black flies that may easily be overlooked. Pipizella larvae confine their attention to subterranean aphids feeding on the roots of plants.
The nine New York species is a fraction of the 126 worldwide species. The Microdon larvae live in the nests of ants as scavengers or predators and unlike other syrphid larvae, have no apparent body segmentation.
The larvae of Syrphinae are predators of aphids and other plant feeding insects. The role in controlling populations if these occasionally destructive "plant lice' is of interest to science as a possible bological control agents. The adult flies are small to medium sized, many with black and yellow patterning. Many species have elongate bodies. The four tribes of the Syrphidae are well represented in New York with the Syrphini being the most divers and numerous of the tribes while Toxomerini contains the most numerous and widespread species Toxomerus marginatus found across new york for much of the summer.
Baccha <small>(Fabricius, 1805)</small> has only one species in New York that is easily overlooked because of its small size.
<small>(Schiner, 1860)</small>
