Barklouse

Natural Habitat

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

Diet & Feeding

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

Behavior Patterns

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).

Risks & Benefits

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.
