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.
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 among what is possibly the most ancient living group of chewing herbivorous insects, dating back to the early Triassic around 250 million years ago.
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.
Melanoplus is a large genus of grasshoppers. They are the typical large grasshoppers in North America. A common name is spur-throat grasshoppers, but this more typically refers to members of the related subfamily Catantopinae.
Romalea is a genus of grasshoppers native to the Southeastern and South-central United States. As traditionally defined, it contains a single species, Romalea microptera, known commonly as the Georgia Thumper,eastern lubber grasshopper, Florida lubber, or Florida lubber grasshopper, although some recent authorities regard Taeniopoda as a junior synonym, in which case there are about a dozen Romalea species in southern United States, Mexico and Central America.
Chorthippus brunneus, also known as the common field grasshopper, is a species of grasshopper of the subfamily Gomphocerinae. The species is common and widespread in the Western Palearctic, and the IUCN lists it as Least Concern.
Saga pedo is a species of wingless bush cricket from the southern half of Europe and western and central Asia. This brown or green bush cricket typically has a total length, from the head to the tip of the ovipositor, of up to 10.5 cm (4.1 in), but exceptionally it may reach 12 cm (4.7 in), which makes it one of the largest European insects and one of the world's largest Orthoptera. The head-and-body alone typically is 5–7 cm (2.0–2.8 in) long in adults, but may reach up to 7.8 cm (3.1 in).
Acridoidea is the largest superfamily of grasshoppers in the order Orthoptera with species found on every continent except Antarctica.
Taeniopoda eques, the western horse lubber grasshopper, is a relatively large grasshopper species of the family Romaleidae found in arid and semi-arid parts of southwestern United States to central and southwestern Mexico. Most populations are identifiable by their shiny black bodies with contrasting yellow markings, but some adults are mostly yellowish, orangish or greenish. The species is unique in using its black coloration to thermoregulate and in being chemically defended. The aposematic coloration warns vertebrate predators of its unpalatability and allows the grasshopper to roost conspicuously upon shrubs.
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. Some species have bright aposematic colours and are highly toxic.
Titanacris albipes, the purple-winged grasshopper, is a large species of South American grasshopper in the family Romaleidae. This species lives in the canopy of the Amazon rainforest and also extends into the Cerrado region in gallery forest. It is often attracted to artificial light during the night.
Poekilocerus pictus, the painted grasshopper, aak grasshopper or ak grasshopper, is a fairly large and brightly coloured species of grasshopper found in India, Pakistan and Afghanistan, especially in drier regions. Both adults and nymphs are toxic; the nymphs are notorious for being able to squirt a jet of noxious liquid at up to around 30 cm (1 ft) away when grasped.
Aularches miliaris is a grasshopper species of the monotypic genus Aularches, belonging to the family Pyrgomorphidae. A native of South and Southeast Asia, the bright warning colours of this fairly large grasshopper keep away predators and their defense when disturbed includes the ejection of a toxic foam.
Schistocerca americana is a species of grasshopper in the family Acrididae known commonly as the American grasshopper and American bird grasshopper. It is native to North America, where it occurs in the eastern United States, Mexico, and the Bahamas. Occasional, localized outbreaks of this grasshopper occur, and it is often referred to as a locust, though it lacks the true swarming form of its congener, the desert locust.
Tropidacris is a Neotropical genus of grasshopper in the family Romaleidae. They are 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. They are variably colored in green, brown, black, reddish or yellowish, and have wings that usually are conspicuously blue or red in flight. The gregarious and flightless nymphs have bright aposematic colors and are presumed to be toxic; a researcher who tasted one noted that it was very bitter, similar to a monarch butterfly.
Cornops aquaticum is a semiaquatic species of grasshopper native to the Neotropics, from southern Mexico south to central Argentina and Uruguay. It feeds and breeds exclusively on members of the aquatic plant family Pontederiaceae, especially water hyacinth, and is being investigated as a possible biological pest control agent for the water hyacinth in countries where that plant is invasive.
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. 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. More typical adult lengths are 5.5–7 cm (2.2–2.8 in), average 6.5 cm (2.6 in), in males and 7–12 cm (2.8–4.7 in), average 11 cm (4.3 in), in females. As suggested by the common name, adult T. cristata have conspicuously red wings in flight, although the exact red hue varies. The flightless and gregarious nymphs have aposematic dark-and-yellow stripes and are presumed to be toxic.
Titanacris is a genus of large grasshoppers in the subfamily Romaleinae and tribe Tropidacrini. They are found from southeastern Mexico, through Central and South America, ranging south to northernmost Argentina.
Cordyceps locustiphila is the basionym and teleomorph of the fungi Beauveria locustiphila, a species of fungus in the family Cordycipitaceae. and is a species within the genus Cordyceps. It was originally described in by Henn in 1904. C. locustiphila is an entomopathogen and obligate parasite of the grasshopper species within the genus Colpolopha or Tropidacris, and as such is endemic to South America. The scientific name is derived from its close relationship with its host, being named after locusts. The fungi was renamed to Beauveria locustiphila in 2017 following research into the family Cordycipitaceae. Following the loss of the species type specimen, new studies were conducted that now recommend that the fungi be divided into 3 species. C. locustiphila, C. diapheromeriphila, and C. acridophila.
