This is a very important pest that has just been discovered in Milwaukee and Ozaukee Counties. Within 2-3 years of infestation it can kill Arrowwood viburnums (V. dentatum) and Cranberrybush viburnums (V. opulus and V. opulus var. americana (formerly V. trilobum)). The Koreanspice viburnum (V. carlesii) is considered resistant but not immune. The symptoms of feeding by the larvae and the beetle consist of oblong holes chewed in the leaves between the veins and scattered over the entire leaf.  Click here to read more about this beetle.
