DESCRIPTION:
Small, black, yellow, and blue striped caterpillars which mature into a blue black moth which resembles a wasp with feather like antennae.
DAMAGE:
Larvae feed side-by-side in groups devouring grape leaves rapidly, leaving only the veins. Soon only the "skeleton" of the leaf remains.
MANAGEMENT:
Hand pick and destroy any adults, larvae, or eggs you see. Wear gloves and a dust mask because the larvae are covered with stinging hairs that may become airborne. Spray plants with Bacillus thuringiensis or carbaryl.
