The Syrphinae constitute one of the three subfamilies of the fly family Syrphidae. Most larvae of this subfamily feed on aphids. It is a monophyletic group with more than 1,600 species.
Platycheirus clypeatus is a species of hoverfly. It is found across the Palearctic and in the Nearctic. The larvae feed on aphids. Adults are usually found on the edges of woodland or scrub, heath or along hedgerows where they visit a wide range of flowers.
Baccha is a genus of hoverflies in the subfamily Syrphinae. They are typically moderate sized with wasp-like bodies. Their larvae are predatory, often on aphids.
Platycheirus is a large genus of hoverflies. They are also called sedgesitters. The genus Platycheirus was established in 1828 by Lepeletier and Serville, with the type specimen of Syrphus scutatus Meigen. This genus is primarily Holarctic in distribution, encompassing 70 species within the Nearctic region. Notably, at least 23 of these Nearctic species are also found in the Palearctic realm, with their approximately 110 species.The distribution of Platycheirus is markedly boreal, with half of the 70 Nearctic species in the Yukon, Northwest Territories, or Alaska. The genus is widespread from Mexico, Central and South America, Europe, Asia, Southeast Asia, Platycheirus are not found in Australia, Indonesia and New Guinea. The genus has a variety of food choices for larvae, ranging from generalized aphid predators to species that specialize in feeding on one or two specific aphid species. Most are feeding within the ground layer of leaf litter.
Platycheirus scutatus is a very common species of hoverfly. It is a Holarctic species.
Pyrophaena is a subgenus of the hoverfly genus Platycheirus distinctive enough to sometimes treated as a separate genus in its own right. Indeed a recent study of the phylogeny of the subfamily Syrphinae found it to be closer to other certain other genera – Rohdendorfia, Syrphocheilosia and Spazigaster. Since only a few species were sampled the true systematic structure must await a more thorough survey of Platycheirus and related genera.
Platycheirus ambiguus is a small widespread species of hoverfly found across the Palearctic from Ireland to Japan. A spring species found in flight in April and May, it visits spring-flowering trees and shrubs, e.g., Prunus spinosa in deciduous woodland and scrub.
Platycheirus angustatus is a species of hoverfly. It is found in many parts of the Palearctic, and in the Nearctic.
Platycheirus immarginatus, the Comb-legged Sedgesitter, is a common species of hoverfly. It is found in parts of northern Europe and northern North America.
Platycheirus confusus, the Confusing Sedgesitter, is a common species of syrphid fly in the family Syrphidae. It has been found to have and eastern and western North American population. Larvae have been successfully reared on a diet of Adelges piceae.
Platycheirus coerulescens, the Hooked Sedgesitter, is a species of syrphid fly in the family Syrphidae.
Platycheirus aeratus, commonly known as Coquillett's sedgesitter, is a species of hoverfly.
Platycheirus inversus, also known as the knobfoot sedgesitter, is a rare species of syrphid fly observed in Northeastern 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. Larvae are aphid predators.
Platycheirus nodosus, known as the twospear sedgesitter, is an uncommon species of syrphid fly observed in Canada and The Rocky Mountains. 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. Larvae are aphid predators.
Platycheirus normae, the paddlearm sedgesitter, is a rare species of syrphid fly observed in northeastern 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. Larvae are aphid predators.
Platycheirus scamboides, the yellowspine sedgesitter, is a rare species of syrphid fly observed in northeastern 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. Larvae are aphid predators.
Platycheirus thompsoni, or Thompson's sedgesitter, is an uncommon species of syrphid fly observed in northeastern 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. Larvae are aphid predators.
Platycheirus varipes is a rare species of syrphid fly observed in Northern Europe: Norway, Sweden, Finland; Greenland; central Asiatic Russia; and in North America from Alaska and Canada south to Colorado, via mountain chains.
Total of 245 species either found or highly expected to be found in New York.
