White apple leafhopper

Typhlocyba pomaria

The white apple leafhopper (WALH) is native to and widely distributed throughout the apple growing regions of North America. The WALH has 2 generations a year and overwinters in the egg stage.
A number of other leafhoppers can be found on apple but none tend to be as serious a pest as the WALH. The potato leafhopper, which migrates into the northern apple growing regions as adults in the spring, is perhaps the most common of the other species that can be found on apple. The two species can be differentiated by the way they walk when disturbed. The WALH walks to the front or backwards while the potato leafhopper walks sideways or "crab like."
