A leafhopper , Graphocephala sp. Photo by C. L. Barr. Leafhopper adults are elongated, wedge shaped and somewhat triangular in cross-section. They jump and fly off readily.
Nymphs resemble adults but are wingless.
They can run rapidly, occasionally sideways, and hop. Most species overwinter as eggs or adults. Eggs are inserted into leaf veins, shoots or stems of host plants. Wingless nymphs hatch from eggs in about 10 days and begin feeding on the tender new growth of their host plant. As nymphs grow larger, they develop wing pads .
