Western potato leafhopper

Leafhoppers are small, light green, wedge-shaped insects that measure a little more than 0.12 inch (3 mm) in length. The western potato leafhopper is a pest throughout California whereas the southern garden leafhopper occurs mostly in the southern California desert areas. Adult females insert kidney-shaped eggs singly in the plant just below the surface. Eggs hatch and the nymphs pass through five instars. Nymphs are whitish to pale green and move rapidly (often sideways) when disturbed. They are found mainly on the underside of leaves.
