Pubic Louse (Crab Louse)

Exclusively inhabits human body hair, most commonly in the pubic region, but occasionally on eyelashes, eyebrows, or chest hair.

Obligate hematophagous; they feed exclusively on human blood several times a day.

They are slow-moving and use their large, crab-like claws to cling to hair shafts. They cannot jump or fly and are usually transmitted via close physical contact or contaminated textiles like bedding.

Causes intense itching (pruritus) and skin irritation (blue spots) due to hypersensitivity to their saliva. They are considered an ectoparasitic infestation (Pediculosis pubis) but do not transmit infectious diseases.
