Lace Bug Nymph (Shed Skin)

Found on the undersides of leaves of various deciduous trees and shrubs, including oak, sycamore, and azalea.

They feed on plant sap by piercing the leaf tissue and sucking out the juices.

The image appears to show an exuvia (discarded exoskeleton) or a nymphs lace bug. They often live in groups on the underside of leaves and go through several molts. They are known for leaving dark, tar-like spots of excrement on leaves.

They are considered garden pests as heavy infestations can cause yellowing (stippling) or silvering of leaves, which may lead to premature leaf drop. They do not bite humans and are generally harmless to people and pets.
