Psocoptera insects Psocids are important insect pests due to their economic impacts on stored commodities and frequent control failures; hence, they are a risk to global food security and safety (Ahmedani et Psocoptera (Insecta) : world catalogue and bibliography. 1933: The lower Permian insects of Kansas; Part 6, Delopteridae, Protelytroptera, Plectoptera and a new collection of Protodonata, Odonata, Megasecoptera, Homoptera, and Psocoptera Proceedings of the American Academy of Arts and Sciences Boston 68: 411-504 This study reports that a common and cosmopolitan insect, the psocid Liposcelis bostrychophila (Psocoptera: Liposcelidae) harbors R.

There are about 30 species, and most booklice inside are wingless. Most authors now use a classification which is essentially that of Badonnel (1951) which is a modification and combination of those of Pearman (1936) and Roesler (1944), together with recent subsequent contributions by many authors in various families.

However, most of the Psocoptera species are found outdoors, in woods and forests, and living in tree barks. That means insect groups whose ancestors once had wings but that have lost them later in evolution. Why the name 'chewing wing' was assigned is unknown and is one of the few names that do not add usefulness to the taxonomy of insects.
