PHOTO COMMENT
These bugs are common in early spring. They appear on grass which they damage by their feeding. Signs of their feeding include bent grass that may have turned red or purple, with whitish patches at the bend location. The bugs are shiny; black, gray or dark copper; with legs that are red or black. Antennae and legs are long and thin. When disturbed they run, fly or drop into foliage.
