The mesothorax is the middle of the three segments in the thorax of an insect, and bears the second pair of legs. The thorax is a division of an Animal 's body that lies between the head and the Abdomen. Insects ( Class Insecta) are a major group of Arthropods and the most diverse group of Animals on the Earth with over a million described Its principal sclerites (exoskeletal plates) are the mesonotum (dorsal), the mesosternum (ventral), and the mesopleuron (lateral) on each side. A sclerite ( Greek skleros meaning " hard " is a hardened body part In Anatomy, the dorsum is the upper side of animals that typically run fly or swim in a horizontal position and the back side of animals (like humans that walk upright In fields of Anatomy, anatomical terms of location are descriptive terms to help identify relative positions or directions within a species The mesothorax is the segment that bears the forewings in all winged insects, though sometimes these may be reduced or modified, as in beetles (Coleoptera) or Dermaptera, in which they are sclerotized to form the elytra ("wing covers"), and the Strepsiptera, in which they are reduced to form halteres. Beetles are the group of Insects with the largest number of known Species. Beetles are the group of Insects with the largest number of known Species. Earwigs is the common name given to the Insect order Dermaptera characterized by membranous wings folded underneath short leathery forewings An elytron (plural elytra) is a modified hardened Forewing of certain Insect orders notably Beetles (Coleoptera and true bugs ( Hemiptera The Strepsiptera (known in older literature as twisted-winged parasites) are an order of Insects with nine families making up about 600 species This article concerns insect anatomy For halteres as used in ancient sports see Halteres (ancient Greece Halteres (hælˈtɪəriːz singular All adult insects possess legs on the mesothorax. In some groups of insects, the mesonotum is hypertrophied, such as in Diptera, Hymenoptera, and Lepidoptera), in which the anterior portion of the mesonotum (called the mesoscutum, or simply "scutum") forms most of the dorsal surface of the thorax. True flies are Insects of the Order Diptera ( Greek: di = two and pteron = wing possessing a single pair of Hymenoptera is one of the larger orders of Insects comprising the sawflies, Wasps Bees and Ants The name refers to Lepidoptera is an order of Insect that includes Moths and butterflies. In these orders, there is also typically a small sclerite attached to the mesonotum that covers the wing base, called the tegula. A tegula is a small Sclerite situated above the base of the Costal vein in the wings of various Insects such as Lepidoptera, Hymenoptera In one group of insects, the Hemiptera, the dorsal surface of the thorax is typically formed primarily of the prothorax, but also in part by the enlarged posterior portion of the mesonotum, called the scutellum; in the Coleoptera, the scutellum may or may not be visible, usually as a small triangular plate between the elytral bases, thus similar in position to the Hemipteran scutellum. Hemiptera is an order of Insects comprising around 80000 Species of Cicadas Aphids Planthoppers Leafhoppers Beetles are the group of Insects with the largest number of known Species. Hemiptera is an order of Insects comprising around 80000 Species of Cicadas Aphids Planthoppers Leafhoppers In Diptera and Hymenoptera the mesothoracic scutellum is also distinct, but much smaller than the mesoscutum. True flies are Insects of the Order Diptera ( Greek: di = two and pteron = wing possessing a single pair of Hymenoptera is one of the larger orders of Insects comprising the sawflies, Wasps Bees and Ants The name refers to
