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 307X, this SEM revealed some of the insect’s exoskeletal morphology exhibited on the cephalic region. Note the two partially visible, bilaterally situated antennae composed of three main segments: visible here was the most proximal scape and the pedicle, and not in the field of view, 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. Its cone-shaped mouth is located at the very top of the image.
