How to identify Japanese beetles

  • Approximately 1/3 to 1/2 inch long.
  • Metallic green head and thorax (the area behind the head) with copper-brown wing covers.
  • Sides of abdomen have five white patches of hairs, and tip of abdomen has two patches of white hair.

Larva (white grubs)

  • C-shaped, white to cream-colored grubs with a distinct tan-colored head.
  • Legs are easy to see.
  • From 1/8 inch up to about one inch long.
  • Japanese beetle grubs look like other white grubs and can only be positively distinguished by examining the pattern of spines and hairs on the underside of the tip of the abdomen.

Japanese beetles were first discovered in Minnesota in 1968. At first, only a few beetles were found. By 2001, they occurred in much higher numbers. In one year the Minnesota Department of Agriculture (MDA) trapped more than one million beetles.

Since then, Japanese beetle numbers have fluctuated from year to year. Japanese beetles are most commonly found in the Twin Cities metropolitan area as well as southeast Minnesota. The MDA maintains an updated distribution map of Japanese beetles.
