Scaeva affinis
North American hoverfly
From Wikipedia, the free encyclopedia
Scaeva affinis, commonly known as the white-bowed smoothwing, is a species of hoverfly found in western North America.[1] The larval form feeds voraciously on aphids.[2] Scaeva affinis is the only Scaeva likely to be encountered in the Nearctic realm, where it is common in the west and rare in the east.[3] This species is believed to be migratory.[4] In 1823, Thomas Say originally described it as "tergum black with three yellow lunules on each side...inhabits Arkansa."[5] S. affinis was later combined with (and then determined to be a distinct species and was split back off from) Scaeva pyrastri.[6]
