The Japanese beetle feeds on the leaves, flowers, and fruit of a wide range of landscape plants. The grubs feed on the roots of many plants and are often damaging to lawns. The adult beetle is approximately 15mm long, with iridescent copper-colored wings and a green head and body. Natural predators restrict damage in its native Japan, but in North America it is a serious pest, feeding on about 200 different species of plants, including rosebushes, grapes, hops, canna, crape myrtles, birch trees, linden trees and others.
