Damsel bugs are slender, grayish, or tan insects that reach about 3/8-inch in length. They have elongated heads, long antennae, and long legs. The first pair of legs is noticeably thicker than the other two pairs.
Damsel bugs overwinter as adults and lay their eggs in plant tissue. Nymphs look much like adults. About three or four generations occur each year.
Damsel bug adults and nymphs suck the body contents from aphids, small caterpillars, leafhoppers, plant bugs, thrips, and mites. They also prey on insect eggs.
