A Technical Report from The Bartlett Tree Research Laboratories 369
Lacebugs are common insect pests on many deciduous and evergreen landscape plants. Common host plants include azalea, sycamore, andromeda (Pieris), oak, hawthorn, hackberry, Rhododendron, crabapple, cherry and serviceberry (Amelanchier). Most lacebugs, such as the azalea lacebug or the sycamore lacebug, are limited to the host genera suggested by the common name, while others such as the hawthorn lacebug attack a variety of related genera. Adult lacebugs are light colored with dark brown or black markings, somewhat square in shape, with wings that appear lacy or similar to a stained-glass window. Nymphs are typically black and may have some spines along their backs or sides.
