Viburnum Leaf Beetle Damage

A leaf beetle that feeds on plants belonging to the genus Viburnum, sometimes causing their death. It is closely related to the elm leaf beetle. Both larvae and adults feed on foliage. Feeding by larvae usually starts on the lower leaf surface and later instars and adults feed throughout the leaf. Larvae can skeletonize young leaves by June. This is the first sign of an infestation. Emerging adults continue feeding on viburnum. Plants that have been defoliated for two or three consecutive years may die. Foliar treatments can be effective and well-timed soil treatments (July) have worked well
