Pubic lice (also called crab lice or "crabs") are parasitic insects found primarily in the pubic or genital area of humans.
Pubic lice may occasionally be found on other coarse body hair, such as hair on the legs, armpits, mustache, beard, eyebrows, or eyelashes. Lice found on the head are generally head lice, not pubic lice.
