The thorax is made up of three segments: the prothorax, mesothorax and the metathorax. Each thoracic segment supports one pair of legs. The meso- and metathoracic segments may each have a pair of wings , depending on the insect. The abdomen consists of eleven segments, though in a few species of insects, these segments may be fused together or reduced in size. The abdomen also contains most of the digestive , respiratory , excretory and reproductive internal structures. Segmentation The head is enclosed in a hard, heavily sclerotized, unsegmented, exoskeletal head capsule, or epicranium , which contains most of the sensing organs, including the antennae, ocellus or eyes, and the mouthparts. Of all the insect orders, Orthoptera displays the most features found in other insects, including the sutures and sclerites. In prognathous insects, the vertex is not found between the compound eyes, but rather, where the ocelli are normally. In some species, this region is modified and assumes a different name. The anterior segment, closest to the head, is the prothorax, with the major features being the first pair of legs and the pronotum.
