Western grape leafhopper

Erythroneura elegantula

The edult grape leafhopper is about 0.12 inch (3 mm) long and light to pale yellow with distinct dark brown and reddish markings. Eggs are laid singly in epidermal tissue on the underside of leaves and appear as a bean-shaped, blisterlike protuberance that is slightly less than 0.04 inch (1 mm) long. Eggs of the first brood are laid in April and May on basal leaves. Nymphs are white with six pale yellow spots on the thorax and clear eyes.
