Annual Bluegrass Weevils are serious pests of close-cut annual bluegrass. Adults are relatively small dark gray Beetles (about 1/8 inch), covered with a yellowish fine hair that falls away as the Weevil matures. Larvae are white, C-shaped grubs with a brown head that eat such plants as rhododendrons.
Army worms are light brown to dark tan, mostly hairless Caterpillars (Moth larva) with yellow or brown stripes that run the length of their 1½ to 2-inch long bodies.
Cutworms are large, up to 2-inch long, hairless caterpillars, the larvae of night-flying moths. Cut worms are a major pest to vegetable gardens, flowers and lawns in the United States. They curl into a "C" shape when disturbed.
Grasshoppers are 1-to 2-inch long insects with powerful legs. They can be green, reddish-yellow or brown. In addition to their large hind legs, they have prominent jaws and fully developed wings. Grasshoppers are voracious feeders, consuming approximately one-half of their body weight per day.
Sod Webworm is a pest especially of bluegrass lawns. The adult is gray-tan, small moth (½ to ¾ inches in length) that flies in an irregular zig-zag pattern over the turf, usually late in the day near dusk. Female moths can deposit as many as 200 eggs. The larvae themselves are ¼ to ¾ inch long gray or light brown caterpillars with black spots. They hide during the day in silky white tubes in the soil, and feed on the turf grass at night.
