A major book-feeding insect is the booklouse (or book louse). It is a tiny (under 1 mm), soft-bodied wingless "psocoptera" (usually "Trogium pulsatorium"). The insect actually eats molds and other plants found in books that were not kept clean and safe, but they will also attack bindings and other parts. It is also not a true louse.
