Primarily a pest of clover and alfalfa. Adults are brown, up to 10 mm long, and have a long snout. They are similar to and larger than alfalfa weevil adults but do not have the dark stripe down the back. Clover leaf weevil larvae begin feeding on plants early in the spring. Infested plants become ragged as the grubs chew out small holes and irregular patches from leaves.
Damage is most severe during late, cool, dry springs.
During wet or humid weather, many larvae are killed by a fungal disease. Alfalfa Insect Forage Control .
