Symptoms: Typical of many sucking type insects and spider mites, leafhoppers leave a stippled color pattern in the leaf that includes white, yellow and light green amongst the green chlorophyll. In severe infestations, leaves may become distorted, turn brown (called leafhopper burn) and drop from the plant.

Diagnosis: The most notable characteristic of leafhoppers is that they have a "wedge shaped" body. They are usually less than 1/2 inch in length and appear to hop and fly away quickly when disturbed. There are several different species of leafhoppers that infest landscape trees and shrubs. Most of them only do minor damage to the trees.

In some species, the eggs spend the winter nestled in the bark of trees and then emerge in the spring. Other species migrate south with the cold weather and then return with the winds in the spring. There may be several generations of leafhoppers during the growing season.

Treatment: If damage is severe enough for treatment, use a pesticide labeled for leafhoppers and be sure to cover the lower surface of the leaves too.
