''Chrotogonus hemipterus'' is a species of grasshopper in the family Pyrgomorphidae. It is a pest of millet Millets () are a highly varied group of small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food.

Grasshopper
Grasshoppers are a group of insects belonging to the suborder Caelifera. They are among what is possibly the most ancient living group of chewing herbivorous insects, dating back to the early Triassic around 250 million years ago. Grasshoppers are typically ground-dwelling insects with powerful hind legs which allow them to escape from threats by leaping vigorously. As hemimetabolous insects, they do not undergo complete metamorphosis; they hatch from an egg into a nymph or "hopper" which undergoes five moults, becoming more similar to the adult insect at each developmental stage. The grasshopper hears through the tympanal organ which can be found in the first segment of the abdomen attached to the thorax; while its sense of vision is in the compound eyes, the change in light intensity is perceived in the simple eyes (ocelli). At high population densities and under certain environmental conditions, some grasshopper species can change color and behavior and form swarms. Under ...

Pyrgomorphidae
Pyrgomorphidae is a family of grasshoppers in the order Orthoptera; it is the only family in the superfamily Pyrgomorphoidea, with a pan-tropical distribution. Their name is probably derived from ''pyrgos'' (Greek: ''Πύργος'') meaning "tower": a reference to the form (''morph'') of the head in the type genus ''Pyrgomorpha'' and other genera. They may sometimes be known as "gaudy grasshoppers", due to the striking, often aposematic colouration of a number of genera; however many others are camouflaged or cryptic, including the genus ''Pyrgomorpha''.

Millet
Millets () are a highly varied group of small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food. Most species generally referred to as millets belong to the tribe Paniceae, but some millets also belong to various other taxa. Millets are important crops in the semiarid tropics of Asia and Africa (especially in India, Mali, Nigeria, and Niger), with 97% of millet production in developing countries. This crop is favored due to its productivity and short growing season under dry, high-temperature conditions. Millets are indigenous to many parts of the world. The most widely grown millets are sorghum and pearl millets, which are important crops in India and parts of Africa. Finger millet, proso millet, and foxtail millet are also important crop species. Millets may have been consumed by humans for about 7,000 years and potentially had "a pivotal role in the rise of multi-crop agriculture and settled farming societies." Descript ...
