Lace Bug

Leaves of trees and shrubs, including azaleas, oaks, and sycamores; often found on the undersides of foliage.

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

They are often seen in groups. Feeding causes 'stippling' or yellow spots on the upper leaf surface. They deposit dark, varnish-like fecal spots on the bottom of leaves.

Generally harmless to humans, though they can occasionally bite if they land on skin, causing minor irritation. They are considered pests as they can cause significant aesthetic and health damage to ornamental plants.
