leafhopper

Tiny triangular or wedge-shaped insects that fly or hop short distances. They are less than 1/5" long, are green, yellow or brownish gray. Many species of leafhoppers infest lawns. They suck the sap from the leaves and stems of the grass. New lawns may be damaged so extensively that reseeding is necessary. Damage to established lawns is evident in whitened patches. It is often mistaken for damage due to dry weather or disease.
