There are three main types of lice that infest humans:
1. Head lice (Pediculus humanus capitis): These are the most common type of lice and are found on the scalp, particularly behind the ears and at the nape of the neck. They feed on blood from the scalp and lay their eggs (nits) on the hair shafts.
2. Body lice (Pediculus humanus corporis): These lice infest clothing and bedding rather than directly living on the body. They only move to the body to feed on blood. Body lice are commonly found in crowded and unhygienic conditions.
3. Pubic lice (Pthirus pubis): Also known as "crabs," pubic lice infest the pubic hair and can also be found in other areas with coarse hair, such as armpits, eyebrows, and eyelashes. They feed on blood and lay their eggs on the hair shafts.
It is important to note that while these three types of lice have specific preferences for certain areas of the body, they can potentially infest other areas as well.
