Under a magnification of 2796X, this scanning electron microscopic (SEM) image is the fifth in a series of five PHIL images, 10106, 10107, 10108, 10109, and 10110, depicting the distalmost exoskeletal morphology found on one of the six legs of an unidentified hornet found in the suburbs of Decatur, Georgia. You are looking at the anatomical configuration of what is termed the leg’s pretarsus, or claw, but in particular the arolium, which is centered between the two distal claws. The insect leg is usually composed of six segments: the proximal coxa, which attaches the leg to the thorax, followed distally by the leg’s trochanter, femur, tibia, tarsus, and pretarsus, which in some insects, as is the case of this hornet, is in the form of a claw.
