Oriental Beetle

Found in lawns, gardens, and agricultural fields in Northeast and Mid-Atlantic regions of the US after introduction from Asia.

Larvae (grubs) eat grass roots and organic matter in soil; adults feed sparingly on various flowers, such as daisies and roses.

Adults are active during the day but are most active during the night; they have a one-year life cycle with peak adult activity in mid-summer.

This beetle is a significant turfgrass pest because the larvae destroy root systems, causing brown patches in lawns; it is not harmful to humans.
