The body of Orthoptera can be divided into three parts: head, thorax, and abdomen. The head contains with face and the antennae. The thorax contains with legs and wings. The abdomen contains with reproductive organs. | |||
Head has the large eyes. The large eyes are compound eyes, because lateral ocellus (placed in front of the each compound eye) and median ocellus (another simple eye which placed on the face view) make to form the eyes. The antennae are called as third eyes. Movable basal segment is called scape, and another movable segment is called pedicel. Rest of the movable antennae is called flagellum, and non movable flagellum is called flagellomere. Lower part of the head has mouth parts. Upper lip is called labrum. Mandibles chew food. Maxillary palpi taste food. Labial palpi is lower lip. The grasshoppers’ cheek is called gena. | |||
Pronotum is an important area for the thorax to identify the species. Front legs are called prothoracic legs, middle legs are called mesothoracic legs, and jumping legs are called metathoracic legs. Narrow forewings are called tegmina. Leading edge of the forewing is called costal margin and trailing edge of the forewing is called inner margin. The wings and the legs are used to produce the sounds by rubbing those. | |||
The abdomen is cylindrical shape with tergites (dorsally over lapping plates) and sternites (ventral plates). End of dorsal and ventral valves make an ovipositor which is used to lay the eggs into the ground. It acts as guiding laying the eggs. Male katydids and meadow grasshoppers has projecting cerci. The crickets have long cerci. The ovipositors have three types: cylindrical, projecting, and flattened and sharply upturned. The true crickets have cylindrical ovipositors. The katydids have projecting and flattened and sharply upturned types of the ovipositor. | |||
