About Japanese Beetle
The Japanese beetle (Popillia japonica) is a 10 mm coppery-green beetle introduced accidentally to New Jersey around 1916 that is now one of the most destructive insect pests of ornamental plants and turf in the eastern United States. Adults skeletonize the leaves of over 300 plant species, feeding from the top in large aggregations guided by pheromone signals. Grubs feed on grass roots underground in late summer, killing irregular patches of lawn. It has no significant natural predators in North America, and its westward spread continues despite decades of management efforts.
