The Japanese Beetle is a small, metallic green insect with coppery-brown wing covers. Adults typically measure about 0.5 inches in length and are known for their distinctive appearance. They are native to Japan but were first identified in the United States in 1916. These beetles are most active during the summer months and are often found on flowers and foliage. The larvae of the Japanese Beetle, known as grubs, live in the soil and feed on grass roots. This can lead to significant damage to lawns and gardens. Effective control methods include insecticides and natural predators, but prevention is key to managing their population.
