The viburnum leaf beetle is restricted to feeding on species of Viburnum. It exhibits a strong preference for the popular arrowwood viburnums, European cranberrybush viburnum, American cranberrybush viburnum, and Rafinesque viburnum. Other viburnums also known to serve as hosts include Sargent viburnum, wayfaringtree viburnum, nannyberry viburnum, and blackhaw viburnum. Particularly resistant species include Koreanspice viburnum, Burkwood viburnum, doublefile viburnum, Judd viburnum, lantanaphyllum viburnum, and leatherleaf viburnum.



Heavy infestations by the viburnum leaf beetle can defoliate shrubs, cause dieback, and eventually kill plants. Valued plantings of the ever-popular European cranberrybush viburnum can be especially ravaged by larval and adult feeding. In addition to the heavy foliage damage caused by larvae and adults, even the inflorescences can be fed upon by larvae. Shrubs repeatedly defoliated over a period of two to three years are likely to die.



The viburnum leaf beetle is not known to occur in Indiana.
