Annual Bluegrass Weevil

Annual Bluegrass Weevil

The annual bluegrass weevil, commonly called “Hyperodes” weevil, is primarily a pest of northeast United States and Canada golf course annual bluegrass turf. The adult weevil is dark brown and may be covered with hair or scales. Adults chew notches in grass stems and deposit up to nine eggs per hole. After hatching, similar to billbugs, the legless larvae tunnel through the stem and into crown area. They emerge above the soil to feed on other plant crown areas. Damage usually appears as small, yellow to brown spots. Two generations of weevil larvae may occur during the year.
