Genus Hammerschmidtia edit

Hammerschmidtia is a Holarctic Genus of hoverflies. The larvae are found in sap under the bark of downed trees.[2] 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.[3]

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.[7] In 1925 Curran reviewed the Genus Neoascia [8]

Genus Orthonevra edit

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 [12] of which N.Y. has O. pictipennis, O. Weemsi and O. pulchella and the Bellula group [13] 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.[12][13]

 
Orthonevra nitida

Genus Sphegina edit

 
Sphegina sp.

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[7] 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.[16] New York species can also be found southward especially in the Appalachian Mountains and also north to the New England States.

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.
