Barklice

Trees with bark, shrubs, and damp vegetation, often found in clusters on the undersides of leaves or on tree trunks

Algae, lichens, fungi, and organic debris found on plant surfaces

They are gregarious insects that often congregate in large groups (sometimes called tree cattle). They exhibit hemimetabolous development (incomplete metamorphosis) and are often seen resting together under fine silk webs they spin for protection.

They are harmless to humans and plants. They are beneficial to the ecosystem because they act as cleaners, scavenging potentially harmful fungi and algae from the bark and foliage of trees and shrubs.
