The thorax and abdomen are segmented and have a rigid cuticle made up of overlapping plates composed of chitin. The three fused thoracic segments bear three pairs of legs and two pairs of wings. The forewings, known as tegmina, are narrow and leathery while the hindwings are large and membranous, the veins providing strength. The legs are ...
Arthropod cuticle is a biological composite material, consisting of two main portions: fibrous chains of alpha-chitin within a matrix of silk-like and globular proteins, of which the best-known is the rubbery protein called resilin. The relative abundance of these two main components varies from approximately 50/50 to 80/20 chitin protein, with ...
Some species may be known as stick grasshoppers or jumping sticks. Within the family Proscopiidae, there are 34 genera and 228 different species. [ 3 ] The proscopiids are herbivores and feed on a variety of plants in a variety of environmental conditions.

Eumastacidae are a family of grasshoppers sometimes known as monkey- or matchstick grasshoppers. They usually have thin legs that are held folded at right angles to the body, sometimes close to the horizontal plane. Many species are wingless and the head is at an angle with the top of the head often jutting above the line of the thorax and abdomen.
Tropidacris cristata, the giant red-winged grasshopper, is a widespread species of lubber grasshopper in the family Romaleidae from tropical South and Central America, and Mexico. [ 1 ] [ 2 ] [ 3 ] It is among the largest grasshoppers in the world by length and wingspan, reaching up to 14.5 cm (5.7 in) and 24 cm (9.4 in) respectively.
The genus name Atractomorpha is derived from the Greek language and means "spindle-shaped" or "arrow-shaped". [8] Various families of Orthoptera (including the Acrididae and Lentulidae) include genera whose species have similarly cone-shaped heads, and there are genera within the family Pyrgomorphidae (such as Phymateus and Dictyophorus) that do not have cone-shaped heads, [9] so their ...
Phymateus is a genus of fairly large grasshoppers of the family Pyrgomorphidae, native to shrubland, semi-deserts, savanna, woodland, gardens and cultivated areas in Sub-Saharan Africa, with ten species in the African mainland and two species in Madagascar. [1] [2] Some species have bright aposematic colours and are highly toxic. [2] [3]
