Japanese Beetles

 The feeding habits of Japanese beetles are what make them such a nuisance. They are opportunistic feeders and have been documented to feed on over 300 types of plants and crops. They also like to feed in groups, which causes them to do damage to a wide area if the food source that attracts them is available. The beetles are most active on warm, sunny days, and prefer plants that are in direct sunlight. Adults feed on the leaves and flowers of the food source. This gives the leaf a “skeletonized” appearance. Adult Japanese beetles are very transient and can infest new areas from several miles away whether it is from wind shift or introduction or food source availability.
