The Psocoptera are tiny insects that have either four wings, two wings or none at all. They have chewing mouthparts and a gradual metamorphosis, the life stages being the egg, nymph, and adult.
Most species occur outdoors on plants, or under bark, stones or dead leaves.
Some of the wingless Psocoptera are called booklice and are found around old books, papers, and in damp, dark rooms. They feed on molds, fungi, pollen, insect fragments and similar materials. The species that occur in-doors rarely cause much damage but are frequently a nuisance. We hope you enjoy visiting our WWW site.
