Problem: Leafhoppers (Boston Ivy)
Erythroneura species Many different species of leafhoppers feed on Parthenocissus. These species also feed on several types of fruit trees and small fruits. The leafhoppers spend the winter as adults in protected areas, usually under fallen leaves or in weeds. When the weather warms in the spring, they fly to plants and feed on the undersides of developing leaves. The leafhoppers suck the fluids from the plant cells, causing the stippled appearance. Adult females insert their eggs into the leaf tissue. The eggs hatch in 2 weeks, and the wingless young leafhoppers feed and develop on the lower surfaces of the leaves. They mature in 3 to 5 weeks. There may be as many as three generations per year.
Spray an insecticide labeled for these pests, following label directions.
