Barklouse

Commonly found on the bark of trees (deciduous and coniferous), often in damp or shaded areas where lichens and fungi grow.

They feed on organic debris, algae, lichens, fungi, and mold found on tree bark; they do not harm the tree.

These insects are often gregarious, especially in their nymph stage, and may form large 'herds' that move together across a tree trunk. They undergo incomplete metamorphosis (egg, nymph, adult).

They are beneficial to the ecosystem as 'cleaners' that graze on fungi and debris. They pose no risk to humans, pets, or the health of the trees they inhabit.
