Identifying Features

The Japanese beetle is 1/2" long. They are metallic copper and green in color, and have white tufts on the sides. Their body is oval, and they have clubbed antennae.

Habitat & Range

The Japanese beetle is native to Asia, and was introduced to the US. It is found in Eastern and Midwestern US, with some sightings further west.


These beetles eat plant roots when larvae, and a variety of leaves as adults. They are a common agricultural pest and are known to feed and move in groups.

Life Cycle

The larvae live in the ground, and emerge as adults in mid-summer. Adults will feed off of foliage and mate. Females lay eggs that will emerge to larvae, that will overwinter.
