Leafhoppers are small slender insects that disperse rapidly when disturbed. They run sideways and are
good jumpers. They are wedge shaped, less than 0.25 inch long as adults, and generally are varying shades
of green, yellow, or brown and often mottled.
Identification of species | Life cycle
Pale stippling on upper surfaces of leaves is characteristic of leafhopper damage. Bleached areas may
enlarge until the leaf becomes mottled or dies, turns brown, and falls. Small white cast skins may be
present. Fruit may be covered with dark, sticky drops of excrement.
Leafhoppers are usually not enough of a problem in home vineyards to justify chemical control measures.
Remove weeds in surrounding areas to prevent the buildup of leafhopper populations that might disperse
to new grape foliage. Rely on natural
soaps can be used if necessary.
