Psocoptera (/ soʊˈkɒptərə /) are a paraphyletic group of insects that are commonly known as booklice, barklice or barkflies. [1] The name Psocoptera has been replaced with Psocodea in recent literature, with the inclusion of the former order Phthiraptera into Psocodea (as part of the suborder Troctomorpha). [2][3][4][5]

Barklice are members of the order Psocoptera, and there are over 300 species in 26 families in the United States and Canada. They are small and, with few exceptions, inconspicuous insects. They are soft-bodied, and usually less than ¼-inch in length, with long antennae and two pairs of wings carried folded over their backs.

Most psocids live outdoors and have wings and are known as barklice. They are found on tree bark, leaves of trees and shrubs, and under stones. They can become obvious when they assemble in large numbers. Barklice feed on fungi, lichen, pollen, decaying plants and other organic material. They are harmless to plants and treatment is not needed.

The barklice are found on trees, feeding on algae and lichen. Psocids are small, scavenging insects with a relatively generalized body plan. They feed primarily on fungi, algae, lichen, and organic detritus in nature but are also known to feed on starch-based household items like grains, wallpaper glue and book bindings. [9] .

The insects of the order Psocoptera (=Copeognatha, Corrodentia) are commonly called psocids, although outdoor species living on tree trunks and branches have been called bark-lice, whereas indoor species, sometimes found in old books, have been called book-lice.
