This illustration depicts some of the morphologic differences seen in two “sucking lice” of the Suborder Annoplura. The louse on the left is a “body louse”, Pediculus humanus var. corporis, and the louse on the right is a “crab” or “pubic louse”, Phthirus pubis. Note that both of these lice are wingless, and possess three pairs of claw-tipped legs, which allows them to firmly grasp the hair shafts to which they remain attached, as human ectoparasitic pests.
