ID#:9244
Description:Caption:
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 76X, this SEM revealed some of the insect’s exoskeletal morphology exhibited on its cephalic, thoracic, and proximal abdominal regions. Of interest is the jointed configuration of its six extremities, from which it derived its classification in the phylum of Arthropoda, i.e., Arthro from "joint”, and poda from "leg"). Also note the sensorial “hairs” known as “setae, which really aren’t hairs at all, but chitinous exoskeletal extensions.
