Annual Bluegrass Weevils
Annual Bluegrass Weevils are serious pests of close-cut annual bluegrass. Adults are relatively small dark gray Beetles (about 1/8 inch), covered with a yellowish fine hair that falls away as the Weevil matures. Larvae are white, C-shaped grubs with a brown head.
The most serious damage is caused by the larvae, which burrow into the stem of the grass, then eat their way out through the crown. The grass will begin to wilt and the turf will develop small, brownish-yellow spots that will spread and connect as the infestation continues. One larva can destroy multiple plants in its lifetime. Adults damage turf grass by chewing notches in the blades.
Annual Bluegrass Weevils are found throughout the Northeastern and
Mid-Atlantic regions including New York, Rhode Island, Massachusetts, New Hampshire, Maine, Vermont, New Jersey, Pennsylvania, Maryland, and most recently Ohio and Virginia.
