Those that do damage grass, however, often escape detection until serious damage has occurred.
Insects feed on the plant roots as well as chewing on leaves and sucking plant juices.
It is important to remember that many insects and even some diseases and fertility problems cause similar looking injury. Identification of the pest based on injury alone is often impossible. The symptoms of insect damage to turf are often more obvious than the insect itself. Use the Key to Turf Insect Damage to aid in insect identification and to determine which detection technique to use. After using this key and narrowing the problem down to an insect or group of insects, then use the appropriate detection technique to find the insect.
