Image of Pediculus humanus Linnaeus 1758

Description:

At a moderate magnification of 309x, this 2006 scanning electron micrograph (SEM) depicted an enlarged dorsal view of the right flexed foreleg of a female body louse, Pediculus humanus var. corporis. The entire leg is not quite visible, but what is visible includes the most distal segment, known as the pretarsus, followed by the more proximal tarsus, then the tibia, femur, and trochanter. The final segment, of the six segments from which each leg is composed, the coxa, is visible under reduced magnification, in PHIL# 9242. In the case of the louse, the leg segments are very stout, and end in claws, which it used to firmly grasp clothing, or a host’s hair shafts.
