A bark-louse is a common name for insects in the order Psocoptera, specifically those found on tree bark. 🌳 They are small, soft-bodied insects that feed on algae, lichens, and fungi. These insects are not parasitic, unlike true lice. 🐛 They are free-living and play a role in breaking down organic matter on trees. Think of them as tiny janitors of the forest. They're a natural part of the forest ecosystem.
