Lace Bug Nymph

Typically found on the undersides of leaves of specific host plants like oaks, sycamores, and azaleas.

Plant juices; they have piercing-sucking mouthparts used to drain sap from the undersides of leaves.

Nymphs often cluster together for protection; they frequently carry a black, sticky excrement (frass) which protects them from predators.

Generally harmless to humans but can occasionally bite if they land on skin; they are pests to garden plants and ornamental trees, causing leaf stippling and yellowing.
