Haematopinus suis, the hog louse, is one of the largest members of the louse suborder Anoplura, which consists of sucking lice that commonly afflict a number of mammals. H. suis is found almost solely on the skin surface of swine , and takes several blood meals a day from its host. [ 1 ]
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 difficult to sever without specialized products. Lice inhabiting birds, however, may simply leave their eggs in parts of the body inaccessible to preening , such as the interior of feather shafts.
Menoponidae is a monophyletic family of lice in the superfamily of chewing lice, Amblycera, often referred to as the chicken body louse family. [1] They are ectoparasites of a wide range of birds including chickens, which makes them important to understand for veterinary science and for human health.
Head louse egg (nit) attached to hair shaft of host. Like most insects, head lice are oviparous. Females lay about three or four eggs per day. Louse eggs (also known as nits), are attached near the base of a host hair shaft. [11] [12] Eggs are usually laid on the base of the hair, 3–5 mm off the scalp surface.
Pubic lice (Pthirus pubis) have three stages: the egg (also called a nit), the nymph, and the adult. They can be hard to see and are found firmly attached to the hair shaft. They are oval and usually yellow to white. Pubic lice nits take about 6–10 days to hatch. The nymph is an immature louse that hatches from the nit (egg).
Argulus foliaceus, also known as the common fish louse, is a species of fish lice in the family Argulidae. [1] It is "the most common and widespread native argulid in the Palaearctic " [ 2 ] and "one of the most widespread crustacean ectoparasites of freshwater fish in the world", considering its distribution and range of hosts.

"Eggs keep in the fridge really well — if you need them, go and get them," said Nelson. Added Metz, "There is a hen for almost every person in the U.S., if they are not in the supermarket today ...
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 ...
