Insects in the family Tettigoniidae are commonly called katydids or bush crickets. They have previously been known as "long-horned grasshoppers". More than 8,000 species are known. Part of the suborder Ensifera, the Tettigoniidae are the only extant (living) family in the superfamily Tettigonioidea.
Orthoptera 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. The order is subdivided into two suborders: Caelifera – grasshoppers, locusts, and close relatives; and Ensifera – crickets and close relatives.
Locusts are various species of short-horned grasshoppers in the family Acrididae that have a swarming phase. These insects are usually solitary, but under certain circumstances they become more abundant and change their behaviour and habits, becoming gregarious. No taxonomic distinction is made between locust and grasshopper species; the basis for the definition is whether a species forms swarms under intermittently suitable conditions; this has evolved independently in multiple lineages, comprising at least 18 genera in 5 different subfamilies.
Mole crickets are members of the insect family Gryllotalpidae, in the order Orthoptera. Mole crickets are cylindrical-bodied, fossorial insects about 3–5 cm (1.2–2.0 in) long as adults, with small eyes and shovel-like fore limbs highly developed for burrowing. They are present in many parts of the world and where they have arrived in new regions, may become agricultural pests.
Grasshoppers are a group of insects belonging to the suborder Caelifera. They are amongst what are possibly the most ancient living groups of chewing herbivorous insects, dating back to the early Triassic around 250 million years ago.
Entomophagy in humans or human entomophagy describes the consumption of insects (entomophagy) by humans in a cultural and biological context. The scientific term used in anthropology, cultural studies, biology and medicine is anthropo-entomophagy. Anthropo-entomophagy does not include the eating of arthropods other than insects such as arachnids and myriapods, which is defined as arachnophagy.
The Caelifera are a suborder of orthopteran insects. They include the grasshoppers and grasshopper-like insects, as well as other superfamilies classified with them: the ground-hoppers (Tetrigoidea) and pygmy mole crickets (Tridactyloidea). The latter should not be confused with the mole crickets (Gryllotalpidae), which belong to the other Orthopteran sub-order Ensifera.
Tetrigidae is an ancient family in the order Orthoptera, which also includes similar families such as crickets, grasshoppers, and their allies. Species within the Tetrigidae are variously called groundhoppers, pygmy grasshoppers, pygmy devils or "grouse locusts".
Metarhizium acridum is the new name given to a group of fungal isolates that are known to be virulent and specific to the Acrididea (grasshoppers). Previously, this species has had variety status in Metarhizium anisopliae ; before that, reference had been made to M. flavoviride or Metarhizium sp. describing an "apparently homologous and distinctive group" of isolates that were most virulent against Schistocerca gregaria in early screening bioassays.

Insect farming is the practice of raising and breeding insects as livestock, also referred to as minilivestock or micro stock. Insects may be farmed for the commodities they produce, or for them themselves; to be used as food, as feed, as a dye, and otherwise.
Insects as food or edible insects are insect species used for human consumption. Over 2 billion people are estimated to eat insects on a daily basis. Globally, more than 2,000 insect species are considered edible, though far fewer are discussed for industrialized mass production and regionally authorized for use in food. Many insects are highly nutritious, though nutritional content depends on species and other factors such as diet and age. Insects offer a wide variety of flavors and are commonly consumed whole or pulverized for use in dishes and processed food products such as burger patties, pasta, or snacks. Like other foods, there can be risks associated with consuming insects, such as allergic reactions. As commercial interest in insects as food grows, countries are introducing new regulatory frameworks to oversee their production, processing, marketing, and consumption.
Acrididea including the Acridomorpha is an infraorder of insects that describe the grasshoppers and ground-hoppers. It contains a large majority of species in the suborder Caelifera and the taxon Acridomorpha may also be used, which excludes the Tetrigoidea. Both names are derived from older texts, such as Imms, which placed the "short-horned grasshoppers" and locusts at the family level (Acrididae). The study of grasshopper species is called acridology.
Pseudophyllus titan, the giant false leaf katydid, is a species of leaf-mimic bush-cricket of the subfamily Pseudophyllinae found in the canopy of tropical forests in Mainland Southeast Asia, Bangladesh, northeastern India, and southernmost China (Yunnan). It is among the largest species in the genus Pseudophyllus, which also makes it one of the world's largest Orthoptera, with a typical length of 13 cm (5.1 in) from head to tip of the folded wings and a wingspan of c. 23 cm (9.1 in). Like many other species of crickets and grasshoppers, the male is capable of stridulation, producing a relatively loud and distinctive, bird-like chirp; it usually stridulates ("sings") at night.
Ruspolia nitidula, the Large Conehead, is a species belonging to the subfamily Conocephalinae of the family Tettigoniidae. It is found throughout Europe, Africa, and the Palearctic part of Asia. A vernacular name that has been used is "cone-headed grasshopper", although it is not a grasshopper, but rather a bush cricket.
Melanoplini is a tribe of spur-throated grasshoppers in the family Acrididae. There are about 19 genera and more than 200 described species in Melanoplini, all in North America. Their biogeography shows that many species in the tribe have descendants from the Eocene epoch and Miocene epoch.
Various cultures throughout Africa utilize insects for many things and have developed unique interactions with insects: as food sources, for sale or trade in markets, or for use in traditional practices and rituals, as ethnomedicine or as part of their traditional ecological knowledge. As food, also known as entomophagy, a variety of insects are collected as part of a protein rich source of nutrition for marginal communities. Entomophagy had been part of traditional culture throughout Africa, though this activity has been diminishing gradually with the influx of Western culture and market economies. Often the collection of insects for food has been the activity of children, both male and female.
