Adult damsel bugs are dull gray or brown and have long, narrow heads with elongated bodies 3/8 to ½ inch long. They have jointed legs and angled antennae. Adults have four wings that make an X-like mark on their backs when the wings are folded. Nymphs look like adults but are darker colored and do not have wings.

Adult damsel bugs and nymphs are very quick moving as they seek slower moving prey. They fly when disturbed.
