Introduction
Barklice (Order: Psocoptera) are small, soft-bodied insects often overlooked due to their size and discreet lifestyle.
Physical Traits
Most barklice are less than 6 mm long, with membranous wings held roof-like over their bodies, although some are wingless.
Habitat
They live on tree bark, foliage, and in leaf litter, where humidity is high and food is abundant.
Diet
Barklice feed on fungi, algae, lichen, and organic detritus—acting as efficient natural recyclers.
Ecological Benefits
By cleaning bark surfaces of microbial growth, they help trees remain healthy and reduce the spread of certain plant diseases.
Social Behavior
Some species form loose colonies, especially in warm and humid environments, and can be seen moving in groups.
