Both species of leafhoppers overwinter as eggs and nymphs begin to emerge shortly after bud break. Stragania apicalis emerges a little later than Macropsis fumipennis . Nymphs and adults feed on petiolules and rachis as opposed to plantbugs which feed on the leaflets. Under a severe infestation, defoliation, and twig die back may occur. The green adults are about five millimetres long.
Females lay eggs in current year's growth, one, and two year old twigs.
There is one generation per season. Populations usually decline in July. Figure 3 Adult leafhopper . Figure 4 Sucking damage from plant bugs and leafhoppers results in stippuled foliage and possible defoliation. Maintaining tree vigour will help affected trees overcome damage caused by infestation.
