Japanese beetle adults are brilliant metallic green, 3/8 to 1/2 inch long, bearing coppery brown wing covers, with five lateral spots with white hairs on each side of the abdomen, and short gray hairs covering the underside of the insect.

In most parts of its range, the Japanese beetle life cycle takes just a year, but in northern areas it may stretch to two years.
