Eastern Sycamore Lace Bug
Corythucha ciliataAlso known as Sycamore Lace Bug, Plane Lace Bug
Eastern sycamore lace bugs are delicate insects with semi-transparent, mesh-like wings that cover their flattened bodies. They feed en masse on the undersides of leaves, draining foliage of chlorophyll and leaving behind a distinctive white stippling along with dark drops of excrement. In cold weather, adults seek refuge beneath peeling tree bark, emerging in spring to colonize new summer leaves.
