Under a magnification of 56X, this scanning electron microscopic (SEM) image depicted some of the exoskeletal morphologic characteristics displayed on the head region of an unidentified beetle, found in the suburbs of Decatur, Georgia. In this particular view, there seems to be numerous hairs growing from the organism’s exoskeletal surface. These structures are sensorial in nature, and are known as setae, providing the insect with information about its environment including thermal changes, changes in wind direction, and the presence of chemicals such as poisons or pheromones.
