Eastern Sycamore Lace Bug

Corythucha ciliata

Also 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.

Responsible observation
  • Leaf inspection: Flip over yellowing sycamore leaves in late summer to spot dense colonies on the undersides.
  • Magnification tip: Use a hand lens or macro lens to observe the intricate lattice pattern of their wings.
  • Bark searching: Look beneath loose strips of sycamore bark in late winter to find hibernating adults.
