Liposcelis bostrychophila is a species of booklouse in the family Liposcelididae. It is known nearly worldwide as a common pest of stored products. It is especially prevalent in cereals. This insect is about a millimeter long, brown in color, and wingless. Females of this species often undergo parthenogenesis. A male specimen was not noted until 2002. A few years later, a sexually reproducing strain was found.
