ID#: 9245
This was one of five scanning electron microscopic (SEM) images (PHIL# 9243 – 9247), magnified at successively higher values, which focused on the head region of a female body louse, Pediculus humanus var. corporis from a ventral perspective. At a magnification of 154X, this SEM revealed some of the insect’s exoskeletal morphology exhibited on its cephalic region. Note the two bilaterally situated antennae composed of three main segments: the most proximal scape, a pedicle, and the multi-segmented flagellum. The antennae, and the insect’s body sport sensorial hairs known as setae, both of which provided the organism with a picture of its environment, by taking readings in thermal, chemical, and mechanical changes encountered in its immediate surroundings.
