Oriental beetle
Rufus Isaacs, MSU Entomology
This pest is established in the eastern United States and is spreading slowly into the Midwest. Adult Oriental beetles vary from light brown to black with mottling on the wing covers.
Adult Oriental beetles.  

They are active from late June through August; slightly earlier than Japanese beetle. They are active at night and can be monitored using a pheromone-baited trap placed on the ground.

The females lay eggs in the ground at the bases of bushes, and larvae feed directly on blueberry roots.


Roots damaged by Oriental beetle.
Larvae are very similar to those of Japanese beetle, but the pattern of hairs on the posterior segment differs, with two parallel rows of 10 to 16 hairs per row.
