Northern New Jersey Cutworms
Dull-brown, gray or nearly black caterpillars that are 1 - 2 inches long. Some cutworms are spotted, others are striped. Usually they hide in the soil during the day and feed at night. They are the larvae of night-flying brown or grayish moths. Cutworms occasionally infest lawns. They feed on the leaves or cut off the grass near the soil and may do severe damage to seedlings of bermudagrass, Bentgrass and ryegrass.
