sucking louse

Any of more than 400 species (suborder Anoplura, order Phthiraptera) of small, wingless, flat ectoparasitic insects found worldwide. They have piercing and sucking mouthparts for extracting their food of mammals' blood and tissue fluids. The nymphs mature after several molts. Species are host-specific: Pediculus infests humans (see human louse), whereas other sucking lice (genera Haematopinus and Linognathus) attack domestic animals, such as hogs, cattle, horses, and dogs.

(invertebrate zoology)
The common name for insects of the order Anoplura, so named for the slender, tubular mouthparts.

[ILLUSTRATION OMITTED] Although generally despised, the blood-sucking human body louse, Pediculus humanus, has gained newfound popularity among scientists for a surprising genetic feature.
There are two species of lice that infest humans: pubic lice, Pthirus pubis, and human head and body lice, Pediculus humanus.
Head Lice, known as Pediculus Humanus in medical parlance, are tiny, flat, wingless insects which often find their way into the scalp as parasites.
