Greenbugs are aphids. Both adults and nymphs are light
green, with a darker green stripe down the back (Color Plate 9). Adults are pear-shaped
and approximately 1.6 mm long. Tips of cornicles and leg segments farthest from the body
are black. Winged and wingless forms may be present in the colony. The bluish-green corn
leaf aphid should not be confused with greenbug. Females without mating produce living
young (nymphs). Under optimal conditions, nymphs become adults in about seven days. Each
female produces about eighty offspring during a twenty-five-day period. |
