The Rocky Mountain locust is an extinct species of grasshopper that ranged through the western half of the United States and some western portions of Canada with large numbers seen until the end of the 19th century. Sightings often placed their swarms in numbers far larger than any other locust species, with one famous sighting in 1875 estimated at 198,000 square miles (510,000 km2) in size, weighing 27.5 million tons and consisting of some 12.5 trillion insects, the greatest concentration of animals ever speculatively guessed, according to Guinness World Records.
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.
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.
Atalopedes campestris is a small grass skipper butterfly. It has a wingspan of 35–41 mm. Male is orange, edged with brown, and has a large brown-black stigma. Female is darker with lighter markings in the center of the wing.
The Balikun jerboa is a species of rodent in the family Dipodidae. It is found in arid areas of northwestern China and Mongolia. It eats green plants, plant roots, seeds, grasshoppers and beetles.
The speckled hind, also known as the calico grouper, kitty mitchell or strawberry grouper, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses.

The differential grasshopper is a species of grasshopper belonging to the genus Melanoplus. It is found throughout northern Mexico, the central United States and southern Ontario, Canada. It is considered a pest over most of its range.
Ichneutica semivittata is a moth of the family Noctuidae. It is endemic to New Zealand. It can be found from the Three King Islands down to Stewart Island. The similar species I. sulcana can be distinguished from I. semivittata as the former is much larger, has a darker hindwing and abdomen and has only one to three spots located behind the middle of the forewing in comparison to the 8 or 9 of I. semivittata. This species lives in a variety of habitats from open grasslands to clearings in forest and at a range of altitudes from the sea level to the alpine zone. Larval host species include Juncus procera, Carex secta as well as on tussock grasses such as Poa cita, P. colensoi and Festuca novae-zelandiae. Adults of this species are on the wing from August to April and are attracted to light.
Zygoballus sexpunctatus is a species of jumping spider which occurs in the southeastern United States where it can be found in a variety of grassy habitats. Adult spiders measure between 3 and 4.5 mm in length. The cephalothorax and abdomen are bronze to black in color, with reddish brown or yellowish legs. The male has distinctive enlarged chelicerae and front femora. Like many jumping spiders, Z. sexpunctatus males exhibit ritualized courtship and agonistic behavior.
Melanoplus bivittatus, the two-striped grasshopper, is a poikilothermic species of grasshopper belonging to the genus Melanoplus. It is commonly found in North America, with high quantities inhabiting Canadian prairies and farmland.
Melanoplus femurrubrum, the red-legged grasshopper, is a species of grasshopper belonging to the genus Melanoplus. It is one of the most common grasshoppers found in Mexico, the United States, and Canada. This grasshopper is frequently used as a model organism in scientific studies, due to their abundance throughout North America and behavioral response to changes in climate.
Spharagemon collare, the mottled sand grasshopper, is found in sandy-soiled, grassy areas of northern United States and southern Canada. They are known to be a minor pest of wheat crops; however, populations are rarely large enough to cause appreciable damage.
Deimatic behaviour or startle display means any pattern of bluffing behaviour in an animal that lacks strong defences, such as suddenly displaying conspicuous eyespots, to scare off or momentarily distract a predator, thus giving the prey animal an opportunity to escape. The term deimatic or dymantic originates from the Greek δειματόω (deimatóo), meaning "to frighten".
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.
Epicauta vittata is a species of beetle in the family Meloidae, the blister beetles. It is native to eastern North America, including eastern Canada and the eastern United States. It is known commonly as the striped blister beetle and the old-fashioned potato beetle. It is known as an agricultural pest.
Euthyrhynchus floridanus, the Florida predatory stink bug, is a species of carnivorous shield bug in the family Pentatomidae, the only species in the genus Euthyrhynchus. It is native to the hottest parts of the southeastern United States and is considered beneficial because it feeds on many species of pest insects. They also feed on things such as grasshoppers and other small insects. This species also hunts in a pack, with up to twelve.
Dissosteira carolina, the Carolina grasshopper, Carolina locust, black-winged grasshopper, road-duster or quaker, is a band-winged species of grasshopper which ranges widely in North America inhabiting weedy grasslands.
Conocephalus fasciatus, the slender meadow katydid, is a species of katydid of the family Tettigoniidae that is native to the United States and Canada.
Usazoros hubbardi, commonly known as Hubbard's angel insect, is a species of insect in the order Zoraptera. It is native to the tropical and subtropical New World and has expanded its range into the eastern United States, where it lives in piles of sawdust, whereas in the hotter part of its range it lives under the bark of decomposing logs. It was named after the American entomologist Henry Guernsey Hubbard, who discovered the insect in the United States.
Eyprepocnemis plorans, the lamenting grasshopper, is a species of insect in the family Acrididae. It is the type species of the genus Eyprepocnemis, and is found in Africa, parts of the Middle East, and southern Europe. It typically inhabits wetlands and other moist habitats.
