Taxoptera graminum (Rondani)

Description and Damage: The adult aphid is about 1 /8 inch long. It is light green with a darker green stripe down its back. The tips of the legs and corni-cle are black. Winged and wingless forms may be present in the same colony. Greenbugs usually feed in colonies on the undersides of leaves. They suck plant juices and inject a toxin. Red spots on upper leaf surfaces and the presence of honeydew are common symptoms. Heavy damage may result in dead leaves and, eventually, dead plants.

Biology: Females produce living young (nymphs) without mating. Under optimum conditions the life cycle is completed in 7 days, and each female pro-duces about 80 offspring during a 25-day period.
