Scaeva affinis (
Say, 1823)
|
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]
