Grasshoppers have a typical insect nervous system, and have an extensive set of external sense organs. On the side of the head are a pair of large compound eyes which give a broad field of vision and can detect movement, shape, colour and distance.
The dorsal tergum, ventral sternum, and the lateral pleura form the hardened plates or sclerites of a typical body segment. In either case, in contrast to the carapace of a tortoise or the cranium of a vertebrate, the exoskeleton has little ability to grow or change its form once it has matured. Except in special cases, whenever the animal ...
Discarded exoskeleton of dragonfly nymph Exoskeleton of cicada attached to a Tridax procumbens (colloquially known as the tridax daisy)An exoskeleton (from Greek έξω éxō "outer" [1] and σκελετός skeletós "skeleton" [2] [3]) is a skeleton that is on the exterior of an animal in the form of hardened integument, which both supports the body's shape and protects the internal organs ...
The male external genitalia have been used widely to aid in distinguishing species, whereas the female external genitalia may be simpler and less varied. The terminalia of adult female insects include internal structures for receiving the male copulatory organ and his spermatozoa and external structures used for oviposition (egg-laying; section ...
This grasshopper has a reddish-brown back, a greenish-yellow belly, and red hind tibiae, hence its specific name femurrubrum (femur = thigh, rubrum = red). Wings of M. femurrubrum typically extend beyond the tip of the abdomen. [2] Males have an enlarged abdomen, with a U-shaped sub-genital plate. [5]
Orthoptera (from Ancient Greek ὀρθός (orthós) 'straight' and πτερά (pterá) 'wings') is an order of insects that comprises the grasshoppers, locusts, and crickets, including closely related insects, such as the bush crickets or katydids and wētā.
Several aquatic insects have similar or alternative closing methods to prevent water from entering the trachea. The timing and duration of spiracle closures can affect the respiratory rates of the organism. [5] Spiracles may also be surrounded by hairs to minimize bulk air movement around the opening, and thus minimize water loss.
In arachnids, the carapace is formed by the fusion of prosomal tergites into a single plate which carries the eyes, ocularium, ozopores (a pair of openings of the scent gland of Opiliones) and diverse phaneres. [2] In a few orders, such as Solifugae and Schizomida, the carapace may be subdivided. In Opiliones, some authors prefer to use the ...
