The Japanese beetle, Popillia japonica Newman (10-15 mm) is distinctively coppery-green with shiny dark brown wing covers (elytra) and five white tufts down each side of the abdomen. Adults feed on the leaves, flowers, and fruits of more than 300 species of plants. The larvae, called white grubs are major turf pests of lawns, parks, and golf courses that cost $450 million dollars annually to control. One generation is produced annually. This invasive species is widespread in Virginia and found throughout much of eastern North America.
