Suborder Anoplura (Order Phthiraptera)
COMMON NAME: SUCKING LICE
The sucking lice are wingless, flat-bodied insects that look much like the chewing lice. The head, however, is narrower than the thorax, and the mouthparts are fitted for piercing the skin and sucking blood. They develop with gradual metamorphosis, the life stages being the egg, nymph, and adult. All adults are wingless. Sucking lice are parasitic on mammals but never attack birds.
Haematopinus suis (Linnaeus) - hog biting louse
Habitat: They can be found all over the hog's body, but prefer to congregate in fold of the skin. Can be harmful to young pigs.
