Japanese Beetles are ½ inch in length with metallic blue-green heads, copper backs, tan wings, and small white hairs lining each side of the abdomen. They usually attack plants in groups, which is why damage is so severe.
They eat the plant material between the veins and any fruit that is growing, effectively preventing the plant from being able to absorb any sunlight.
Trees and Plants Affected
Adult Japanese beetles chew on leaves and flowers of over 300 different plants and trees. They seem to favor roses, fruits and vegetable crops, along with linden, plum, cherry, Norway maple and crabapple trees. Chewing by adults occurs in early summer at the top of the plant or tree first. This chewing creates a lacy, skeletal appearance to leaves and flowers until the plant material turns brown and dies.
Japanese Beetle Traps and Control
The increase of Japanese beetle numbers over the last few years has been a concern. Control measures are available, but applications must be properly timed to have the most impact. Japanese beetle traps must be placed strategically to keep the beetles away from your plants and trees. Other factors must be considered, such as bee foraging and minimizing impacts to non-target insects that help trees.
