Clover seed-Lygus bug

Lygus spp.

Pest description and crop damage Adults are 0.2 inch long with a light yellow V on the back. Lygus bugs pierce and damage meristematic tissue causing blasted buds, blossom drop, and shriveled seed. Lygus bugs reduce yields of alsike and Ladino clover seed but are not considered a pest of red clover. Clover seed weevil treatments usually control lygus on white clover.
