Magnified 103X, this scanning electron micrograph reveals some of the minute exoskeletal details found on the surface of what is thought to be a mosquito discovered in the suburbs of Decatur, Georgia. In this particular view portions of the thoracic and abdominal regions are visible with this insect's jointed legs in the foreground, emanating from its thoracic region. As a member of the Phylum Arthropoda, this insect is supported by a jointed exoskeleton, thereby facilitating mobility of all of its body parts. Arthropods possess an exoskeleton composed of chitin, which is a molecule made up of bound units of acetylglucosamine, joined in such a way as to allow for increased points at which hydrogen bonding can occur. In this way chitin provides increased strength and durability as an exoskeletal foundation. This chitinous exoskeleton gives rise to a myriad of morphologic shapes, including scales, setae, antennae, legs, and mouthparts.
