Pubic lice ( Crabs ) Image Source: By Doc. RNDr. Josef Reischig, CSc. - Author's archive, CC BY-SA 3.0, https://commons.wikimedia.org/w/index.php?curid=31557499 1. Pubic lice are tiny parasitic insects that live in coarse body hair, such as pubic  hair. They are yellow-grey and about 2mm long. They have a crab-like appearance so  they are often known as crabs. The eggs appear as brownish dots fixed to coarse body  hair. Pubic lice are different from the head lice which some people get on their  scalp. 2. Parasitic lice belong to the insect order Phthiraptera and include two main groups.  The group that includes the human lice is known collectively as "Anoplura" , or the  sucking lice. There are over 550 species in the world, all of which are blood-sucking  parasites of mammals, including wildlife, livestock, and pets. 3. The second group contains the chewing lice, known collectively as "Mallophaga" .  This is a large and diverse assemblage of over 2,650 species

Head Lice - A Lousy Problem Image source:   By Gilles San Martin - originally posted to Flickr as Male human head louse, CC BY-SA 2.0, https://commons.wikimedia.org/w/index.php?curid=11208622 1. Three types of sucking lice infest humans: the body louse, the head louse and the  crab louse or pubic louse. 2. The head louse and the body louse are physically indistinguishable, but are easily distinguished from the crab louse . Head lice (also known as "head louse") are small  insects that live in people's hair and feed on their blood.  3. Lice glue their eggs (also known as "nits") to hair so they cannot be brushed or  shaken off easily. Lice eggs take about six to nine days to hatch. After they have  hatched they take about seven or more days to become egg-laying adults.  4. Lice die very quickly (usually about two days) without feeding and cannot live for  very long away from a person's head. 5. They need blood to survive and can live up to 30 days on the head
