Under a very low magnification of only 11X, this scanning electron micrograph (SEM) depicted some of the morphologic details found on the exoskeletal surface of an unidentified hornet discovered in the suburbs of Decatur, Georgia. In this particular view, which centers on the insect's body where its midsection, or thorax, attaches to its abdomen by the 'petiole', you'll note its two forewings, left hindwing, and sensorial 'hairs' covering almost the entire exterior. Like its exoskeleton, all of these structures are composed of 'chitin'.
