  • Another beetle that may be found feeding on a wide variety of ornamental plants is the Asiatic garden beetle (see above photo).
  • Adults are about 3/8" long and feed on about 30 plants including rose, sumac and viburnum.
  • Adults are nocturnal and are seldom seen. They can be attracted to outdoor lights.
  • The beetles begin feeding at the leaf edge and may consume the entire leaf leaving only the midrib.
  • Check damaged plants at night for the presence of the beetles.
  • Heavy infestations may require the application of a residual insecticide to protect flowers and foliage of desirable plants.
  • The larvae or grubs feed on turf roots.
