The body louse (Pediculus humanus humanus, also known as Pediculus humanus corporis) or the cootie is a hematophagic ectoparasite louse that infests humans. [1] It is one of three lice which infest humans, the other two being the head louse , and the crab louse or pubic louse .
Additionally, the DNA differences between head lice and body lice provide corroborating evidence that humans used clothing between 80,000 and 170,000 years ago, before leaving Africa. [34] Human head and body lice occupy distinct ecological zones: head lice live and feed on the scalp, while body lice live on clothing and feed on the body.
Pediculus humanus is a species of louse that infects humans. It comprises two subspecies: [1] [2] Pediculus humanus humanus Linnaeus, 1758 – body louse; Pediculus humanus capitis De Geer, 1767 – head louse

Scientists have long debated whether human body lice might have helped drive the rapid spread of the bacteria responsible for the deadly plague in the Middle Ages, known as the Black Death.
Pediculus is a genus of sucking lice, the sole genus in the family Pediculidae. Pediculus species are ectoparasites of primates. Species include: [1] Pediculus clavicornis Nitzsch, 1864; Pediculus humanus Linnaeus, 1758. Pediculus humanus humanus Linnaeus, 1758 – the body louse; Pediculus humanus capitis De Geer, 1767 – the head louse ...
An adult crab louse is about 1.3–2 mm long (slightly smaller than the body louse and head louse), and can be distinguished from those other species by its almost round body. Another distinguishing feature is that the second and third pairs of legs of a crab louse are much thicker than the front legs and have large claws. [6]
