Leafhoppers are small (0.1 to 0.3 inch), wedge-shaped insects that congregate on the undersides of leaves, feeding by piercing plant tissue and sucking sap.

Monitor ornamental and fruit tree foliage starting in May by examining leaf undersides and checking upper surfaces for stipple. For light populations, a strong water spray dislodges insects. Apply insecticidal soap or horticultural oil targeting insects; repeat every 7 to 10 days. Neem oil applied to undersides can be effective. Maintain plant vigor through appropriate watering.
