Apple-Eyespotted bud moth

Spilonota ocellana

Pest description and crop damage Adults are grayish moths about 0.4 inch long with a wide white band on each forewing. Larvae are chocolate-brown with black heads, and up to 1 inch long. The eyespotted bud moth does not usually require control on apples.

Biology and life history Larvae spend the winter in a cocoon on the bark in the crotches of small-diameter limbs. They become active around budbreak and feed on leaves and buds, webbing together leaves and feeding within these nests. After feeding they pupate within the nest and adult moths emerge in early to mid-summer. Eggs are laid on the lower surface of leaves. The larvae emerge and feed on the lower leaf surface until early August, at which time they construct their overwintering cocoons (hibernacula).

Sampling and thresholds Look for larvae in nests of webbed-together leaves in the spring.
