Leafhoppers are rarely a problem on lawns, except when there’s a massive infestation. They will feed on all grass types, leaving them yellow or “bleached.” Leafhoppers are small, winged, wedge-shaped insects that look a little bit like a grasshopper. While they are usually green, yellow or gray, the candy striped leafhopper is has brilliant blue and orange patterns on its back.
Leafhoppers are very small, and measure only up to a ¼ inch long. It's their small size that makes them easy to ignore. Aside from grass, they may also feed on roses, potato plants, grape vines and apple trees. Some gardeners say their damage looks a lot like spider mites.
