Insects that damage grass are leafhoppers, mites, spittlebugs, and chinch bugs. Usually only the chinch bug is severe enough to require control measures. Leafhoppers are long, wedge-shaped insects that hop or fly short distances. They are often brightly colored and have stripes. The basic color may be green, yellow, or brown.
Leafhoppers suck plant juices from many plants including grasses.
The damage they cause is chlorosis, a disease marked by white or yellow patches on green blades. Mites also suck plant juices. The damage they cause is a blotching or stippling of grass blades. Sometimes, under heavy infestations, a silk-like webbing is visible. One mite pest, the clover mite, leaves grasses and enters homes in spring or fall.
