Lace Bug

Typically found on the undersides of leaves of various host plants including ash, oak, sycamore, and ornamental shrubs.

Herbivorous; they use piercing-sucking mouthparts to feed on plant sap from the underside of leaves.

They are known for leaving dark, varnish-like droplets of excrement on leaves. They go through incomplete metamorphosis (egg, nymph, adult) and often have multiple generations per year.

Generally considered a landscape pest that causes 'stippled' or bleached-looking leaves and premature leaf drop. They do not bite humans or pets and have little to no ecosystem benefit within a garden setting except as a food source for predatory insects.
