Japanese Beetle

Grassy areas, gardens, farms, and forests across North America and parts of Asia and Europe

Adults are generalist herbivores that feed on the foliage, flowers, and fruits of over 300 plant species; larvae feed on the roots of grasses.

Adults are active during the day and group together to feed (gregarious feeding). They exhibit a complete metamorphosis cycle: egg, larva (grub), pupa, and adult.

Regarded as a highly destructive invasive pest. They cause significant damage to ornamental plants, crops, and turfgrass. Benefits are minimal, though they can serve as a food source for some birds and small mammals.
