Other lice that infest humans are the body louse and the crab louse (aka pubic lice). The claws of these three species are adapted to attach to specific hair diameters. [18] Pubic lice are most often spread by sexual contact with an infested person. [19] Body lice can be found on clothing and they are not known to burrow into the skin. [20]
Mallophaga develop by gradual metamorphosis. Females typically lay 150–300 eggs over an interval of 2–3 weeks. The eggs, commonly known as nits, are oblong and around 1 mm long. The eggs are glued to the hairs or feathers of the host with a secretion from the female accessory glands.
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 ...

When your child is the temporary home for these blood-sucking freeloaders, the social issue can sometimes be more overwhelming than the physical issue.
The life cycle of the body louse consists of three stages: egg, nymph, and adult. Eggs (also called nits, see head louse nits) are attached to the clothes or hairs by the female louse, using a secretion of the accessory glands that holds the egg in place until it hatches, while the nits (empty egg shells) may remain for months on the clothing ...
Accordingly, the infestation with head lice is named pediculosis capitis, while this with body lice, pediculosis corporis. [ 1 ] [ 2 ] Although pediculosis in humans may properly refer to lice infestation of any part of the body, the term is sometimes used loosely to refer to pediculosis capitis , the infestation of the human head with the ...
Lice may transmit microbial diseases and helminth parasites, [22] but most individuals spend their whole life cycle on a single host and are only able to transfer to a new host opportunistically. [7] Ischnoceran lice may reduce the thermoregulation effect of the plumage; thus heavily infested birds lose more heat than others. [ 23 ]
