- Another leaf-feeding beetle along the lines of the Japanese 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 beetles.
- To reduce their numbers handpick beetles in the evening when they are feeding and drop them into a container of soapy water.
- 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.
