Plum curculio (Conotrachelus nenuphar) adults are 1⁄4 inch long snout beetles with dark brown with patches of white or gray. Four prominent humps are present on wing covers. Larvae are legless, grayish-white grubs with brown heads, and are 1⁄3 inch long when full-grown. Injury will appear as 1⁄8-inch crescent-shaped cuts on fruit surfaces.
