The head louse (Pediculus humanus capitis) is an obligate ectoparasite of humans. [1] Head lice are wingless insects that spend their entire lives on the human scalp and feed exclusively on human blood. [1] Humans are the only known hosts of this specific parasite, while chimpanzees and bonobos host a closely related species, Pediculus schaeffi.
Louse (pl.: lice) is the common name for any member of the clade Phthiraptera, which contains nearly 5,000 species of wingless parasitic insects. Phthiraptera has variously been recognized as an order, infraorder, or a parvorder, as a result of developments in phylogenetic research. [1][2][3] Lice are obligate parasites, living externally on ...
Common [5] Head lice infestation, also known as pediculosis capitis, is the infection of the head hair and scalp by the head louse (Pediculus humanus capitis). [6] Itching from lice bites is common. [5] During a person's first infection, the itch may not develop for up to six weeks. [5] If a person is infected again, symptoms may begin much ...
[14] [15] Normally head lice infest a new host only by close contact between individuals, making social contacts among children and parent child interactions more likely routes of infestation than shared combs, brushes, towels, clothing, beds or closets. Head-to-head contact is by far the most common route of lice transmission. [citation needed]

Braulidae, or bee lice, is a family of true flies (Diptera) with seven species in two genera, Braula and Megabraula. [2] They are found in honey bee colonies due to their phoretic, inquiline, and kleptoparasitic relationships with the bees. Similar in appearance but not closely related to keds, these flies are also small, wingless, and ...
Woodlouse. Woodlice are terrestrial isopods in the suborder Oniscidea. Their name is derived from being often found in old wood, [2] and from louse, a parasitic insect, [3] although woodlice are neither parasitic nor insects. Woodlice evolved from marine isopods which are presumed to have colonised land in the Carboniferous, though the oldest ...
