Female lice are usually more common than males, and some species are parthenogenetic, with young developing from unfertilized eggs. A louse's egg is commonly called a nit. Many lice attach their eggs to their hosts' hair with specialized saliva; the saliva/hair bond is very
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 ...
The amber eggs are deposited on the lower half of the swine's side, or the neck, shoulders, flanks, or on the back of the ears. Lice eggs are commonly referred to as "nits". [Note 1] These nits have small holes for gas exchange, called opercula. Typically, eggs will hatch within 12–14 days, but this varies depending on temperature. [4]
Pediculosis pubis (also known as "crabs" and "pubic lice") is an infestation by the pubic louse, Pthirus pubis, a wingless insect which feeds on blood and lays its eggs (nits) on mainly pubic hair. Less commonly, hair near the anus, armpit, beard, eyebrows, moustache, and eyelashes may be involved.
The eggs of the crab louse are laid usually on the coarse hairs of the genital and perianal regions of the human body. The female lays about three eggs a day. The female lays about three eggs a day. The eggs take 6–8 days to hatch, and there are three nymphal stages which together take 10–17 days before the adult develops, making a total ...
Pthirus is a genus of lice. There are only two extant species, and they are the sole known members of the family Pthiridae. [4] Pthirus gorillae infests gorillas, [5] and Pthirus pubis afflicts humans, and is commonly known as the crab louse or pubic louse. [6] The two species diverged some 3.3 million years ago. [7]
Head lice have been constant, if unwanted, human companions. The parasites are rich sources of genetic information illuminating big questions in the human story.
Also, names might not be the commonly accepted English-language terms for a particular topic. However, with food dishes, non-English names are often adopted into the culture, such as with " Huevos rancheros " as an egg dish found in Tex-Mex cuisine .
