Hammerschmidtia rufa, The Black-bristled Logsitter is an uncommon species. Hammerschmidtia sedmani Pale-bristled Logsitter is a rare species in N.Y.
Genus Myolepta
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
Myolepta strigilata
M. nigra
M. varipes
Genus Neoascia
Neoascia (Williston, 1886) Fen Flies
These are very small (3.5–5 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
Neoascia metallica (Williston, 1882 ) The Double-banded Fen Fly, is a common species. Neoascia tenur (Harris, 1780) The Black-kneed Fen Fly is a common species that was formerly considered to be only European now considered to be throughout North America and Canada.

Genus Orthonevra
Four species Orthonevra (Macquart, 1829) 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. Orthonevra nitida (Wiedemann, 1830) The Wavy mucksucker is a fairly common species.
Orthonevra pictipennis (Loew, 1863) Dusky-veined Mucksucker is an uncommon species. Orthonevra pulchella (Williston, 1887) The Dusky Mucksucker is a fairly common species. Orthonevra weemsi (Sedman, 1966) Weems' Mucksucker is a rare species.
Genus Sphegina
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. There are various keys online, Covert 1977 Hull, 1935 and Malloch, 1922
