Pest Status: Booklice are also called psocids. They are sometimes a nuisance pest in homes and other buildings, but are usually innocuous.
Appearance: Pscocids are very small, white, soft-bodied insects that may or may not have wings. Their uniquely enlarged clypeus (mouthparts) set them apart from other small insects.
Life Cycle: Females deposit egg cases in clusters often inside webbing or in papers or books. They feed on molds, fungi, and sometimes pollen in these areas.
Where to Collect: Booklice are usually found in humid environments where molds may grow on old papers or books.
