Adult Japanese beetles skelotonize leaf tissue. Fruit feeding is less common, and usually occurs only if the fruit has been previously damaged or is over mature. Most damage typically occurs late in summer or early fall. The beetle overwinters as a larva in the soil. Adults emerge in mid-June to July.
Adults are bright metallic-green with coppery red wings and small white tufts on the sides and tip of the wing covers (about 12mm).
