While the leaves of viburnum (Viburnum spp.) shrubs have fallen, if the viburnum leaf beetle (Pyrrhalta viburni) was present earlier this year, the eggs laid on the shrubs newest growth will be evident. This non-native invasive species feeds a larvae and adult, skeletonizing viburnum leaves. When population level of the insect increase, defoliation of the shrub becomes more obvious. The insect will feed on naturally growing viburnums, as well as those planted in landscapes, in commercial plantings and at gardens and arboretums.
