Thus, mobile head lice populations may contain eggs, nits, three nymphal instars, and the adults (male and female) . [1] Metamorphosis during head louse development is subtle. The only visible differences between different instars and the adult, other than size, is the relative length of the abdomen, which increases with each molt, [ 1 ] as ...
Adults can live for about thirty days, but if they are separated from their host they will die within two days. [12] If the conditions are favorable, the body louse can reproduce rapidly. After the final molt, female and male lice will mate immediately. A female louse can lay up to 200–300 eggs during her lifetime. [13]
Lice inhabiting birds, however, may simply leave their eggs in parts of the body inaccessible to preening, such as the interior of feather shafts. Living louse eggs tend to be pale whitish, whereas dead louse eggs are yellower. [5] Lice are exopterygotes, being born as miniature versions of the adult, known as nymphs. The young moult three ...
Adults are 1.5–2.0 mm long and flattened. They are much broader in comparison to head and body lice. Adults are found only on the human host and require human blood to survive. Pubic lice are transmitted from person to person most-commonly via sexual contact, although fomites (bedding, clothing) may play a minor role in their transmission. [4 ...

From each egg or "nit" may hatch one nymph that will grow and develop to the adult louse. Lice feed on blood once or more often each day by piercing the skin with their tiny needle-like mouthparts. While feeding they excrete saliva, which irritates the skin and causes itching. [8] Lice cannot burrow into the skin. [citation needed]
Most adult species are light tan to brown in color and are usually 1–4 mm in length, although some livestock species can grow to be 5–7 mm, and some wild bird species can even get to 10 mm. [2] Mallophaga are often adapted to live on a specific part of their host and typically spend their entire lives on a single host.
