Too numerous to mention. Cutworms and armyworms are the caterpillars of several species of night-flying moths.
Cutworms are plump, smooth and often, greasy-looking.
Typically, cutworms curl up tightly when disturbed. Although about the same size, the armyworms differ in appearance. True armyworms are plump, sparsely-haired, generally green to brown larvae, with dark stripes running down the sides and back. In contrast, fall armyworm larvae have more conspicuous, longer hairs located on definite black tubercles and an inverted Y-shaped suture located at the front of the head. These caterpillars feed on the aboveground plant parts of many grasses and is a pest of many garden and field crops.
