Booklouse

/ˈbʊkˌlaʊs/ noun

Definition

A singular tiny insect of the order Psocoptera that feeds on mold and organic materials found in old books and damp environments.

Etymology

Singular form of 'booklice,' from 'book' and 'louse' (Old English 'lūs'). Also called psocids or dust lice, these insects were named for their association with stored books.

Kelly Says

The booklouse is actually ancient—fossils show similar insects existed for over 300 million years, far predating writing. But they discovered books make a great home once humans invented them.
