Winged female Pea aphid? - Acyrthosiphon pisum
Las Cruces, Dona Ana County, New Mexico, USA
March 1, 2016
Populations of Acyrthosiphon pisum are starting to build up in alfalfa.
I consider this ID as tentative. Although this is one of the most common aphid species in alfalfa-growing regions, if confirmed, this will be the first entry for New Mexico.
