Japanese beetles can be a devastating insect to many plants in the landscape.
Coppery brown wings covers do not completely cover the body, leaving exposed a row of five spots of white hairs down each side of body. The Japanese beetle overwinters as a partially grown grub in the soil. In early spring, the grub resumes feeding on turfgrass roots. Pupation occurs near the soil surface where the grub transforms into the colorful adult beetle stage. Adult emergence occurs as early as the last of May in the Southeast and as late at mid-July in the Midwest.
