Lace Bug

Lace Bug
Most Lace Bugs are found in elm, hackberry, oak, sycamore, basswood, and other hardwood trees. Adults are flat, 5 to 6 mm long, and dark-colored with highly sculptured (lace-like) white wings. There are usually two overlapping generations per year; thus all life stages can be found on the lower surface of leaves throughout the summer. Lace bugs overwinter in protected places on the tree. Infested leaves have brown or yellow stippling from feeding punctures and tar-like defecation spots. Because severely damaged leaves turn brown and droop prematurely, heavily infested trees may be defoliated, especially during dry weather.
