Japanese beetle adults feed on flowers and leaves of hundreds of plant species. They are often found in large groups feeding on plants.
The grubs are curved, creamy white with dark ends and look like many other insect grubs found in soil.
Grubs feed on turf grass, landscape, and garden plants. They damage large areas of turf grass. Japanese beetle is the most widespread turf grass pest in the United States.
