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.
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".
Autohaemorrhaging, or reflex bleeding, is the action of animals deliberately ejecting blood from their bodies. Autohaemorrhaging has been observed as occurring in two variations. In the first form, blood is squirted toward a predator. The blood of these animals usually contains toxic compounds, making the behaviour an effective chemical defense mechanism. In the second form, blood is not squirted, but is slowly emitted from the animal's body. This form appears to serve a deterrent effect, and is used by animals whose blood does not seem to be toxic. Most animals that autohaemorrhage are insects, but some reptiles also display this behaviour.
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.
Deinacrida connectens, often referred to as the alpine scree wētā, is one of New Zealand's largest alpine invertebrates and is a member of the Anostostomatidae family. Deinacrida connectens is a flightless nocturnal insect that lives under rocks at high elevation. Mountain populations vary in colour. This species is the most widespread of the eleven species of giant wētā (Deinacrida).
The Copiphorini are a tribe of bush crickets or katydids in the family Tettigoniidae. Previously considered a subfamily, they are now placed in the subfamily Conocephalinae. Like some other members of Conocephalinae, they are known as coneheads, grasshopper-like insects with an extended, cone-shaped projection on their heads that juts forward in front of the base of the antennae.
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 of bush cricket 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.
Scudderia furcata is a species in the family Tettigoniidae ("katydids"), in the order Orthoptera. A common name for Scudderia furcata is fork-tailed bush katydid. The distribution range of Scudderia furcata includes Middle America and North America. The nymphs of this species can be pests of citrus fruit.
Oecanthus nigricornis is a "common tree cricket" in the subfamily Oecanthinae. A common name for O. nigricornis is black-horned tree cricket. It is found in North America.
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.
