Cutworm damage to an expanding bud. Tom Zabadal
Climbing cutworms are large, smooth caterpillars measuring 30 to 40 mm when fully grown. The head capsule is usually dark and the body is dull gray-brown, marked with dots or stripes, and curled when disturbed. The larvae overwinter in the soil of the vineyard floor and become active in spring when vine buds begin to expand. Larvae feed on young buds at night, hiding in the soil beneath the vines during the day. Cutworms are mainly a pest in areas with sandy soils and in vineyards with weeds under the vines.
