A wide range of garden, ornamental, and forage plants as well as many weeds and grasses are subject to infestation by this fleahopper. Garden fleahoppers cause pale spots to develop on leaves by sucking sap from the foliage. Heavily infested foliage dies and drops from the plant. Such defoliation interferes with growth and development of the crop. History- Garden fleahoppers overwinter as eggs laid from August through September.
Nymphs emerge in early spring and feed on undersides of leaves.
Nymphs feed and develop from 11 to 35 days before maturing into adults. The duration depends on temperature. Adults live 1 to 3 months. Each female lays approximately 105 eggs. Eggs are inserted into punctures made by the mouthparts in stems or leaves.
