Lice are in the order Phthiraptera, which contains some 5,000 species in four suborders.
The female louse attaches eggs, known as nits, to the shaft of human hair using a cement-like substance from her reproductive organ.
A louse cannot live by blood alone; most blood-sucking lice depend on symbiotic bacteria in their guts to provide vital nutrients.
Completely unrelated to the lice that parasitize birds and mammals are the invertebrates known as Psocoptera, the barklice and booklice. Some feed on bark and lichen on trees; others are “bookworms,” pests of libraries large and small.
