The Grapeleaf Skeletonizer Moth is a small, slender black moth with a bright orange collar that gives it an elegant, wasp-like appearance. Its brightly colored gregarious caterpillars skeletonize the leaves of wild and cultivated grapes, feeding in lines from the leaf edge inward. Their vivid yellow coloration warns of sequestered toxic chemicals from host plants.
