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.
Gryllinae, or field crickets, are a subfamily of insects in the order Orthoptera and the family Gryllidae.
William Henry Cade is an American-Canadian biologist who served as the president and vice-chancellor of the University of Lethbridge from 2000 to 2010. His research articles deal mainly with entomology, particularly with field crickets.
Ormia ochracea is a small yellow nocturnal fly in the family Tachinidae. It is notable for its parasitism of crickets and its exceptionally acute directional hearing. The female is attracted to the song of the male cricket and deposits larvae on or around him, as was discovered in 1975 by the zoologist William H. Cade.
Gryllus bimaculatus is a species of cricket in the subfamily Gryllinae. Most commonly known as the two-spotted cricket, it has also been called the "African" or "Mediterranean field cricket", although its recorded distribution also includes much of Asia, including China and Indochina through to Borneo. It can be discriminated from other Gryllus species by the two dot-like marks on the base of its wings.
Teleogryllus oceanicus, commonly known as the Australian, Pacific or oceanic field cricket, is a cricket found across Oceania and in coastal Australia from Carnarvon in Western Australia and Rockhampton in north-east Queensland
Tree crickets are insects of the order Orthoptera. These crickets are in the subfamily Oecanthinae of the family Gryllidae.
Gryllotalpa major,also known as the prairie mole cricket, is endemic to the United States and is the largest cricket in North America. Its natural habitat is temperate grassland and it belongs to the family Gryllotalpidae. It is threatened by habitat loss, and is currently only found in Oklahoma, Kansas, Missouri, Nebraska and Arkansas. Males of this species produce sounds by rubbing their fore wings together. They sing from special burrows they construct in the prairie soil to attract females for mating, and they can be heard at distances up to 400 m from the burrow. Males aggregate their acoustic burrows in a lek arena and are very sensitive to vibrations carried through the ground. Males communicate with neighboring males through vibrational signals, and the songs they project to flying females are harmonic chirps, rather than the trills produced by most mole crickets.
Gryllus pennsylvanicus is known as the fall field cricket. G. pennsylvanicus is common in southern Ontario, is widespread across much of North America and can be found even into parts of northern Mexico. It tends to be absent in most of the southwestern United States including southern California. Within its geographic range this field cricket will burrow into soil in fields and forest edges. Individuals inhabit grassy disturbed areas and are often found around areas of human habitation.
Gryllus veletis, commonly known as the spring field cricket, is abundant throughout eastern North America. G. veletis is a solitary, aggressive, omnivorous, burrow-inhabiting species of cricket. This species is commonly confused with Gryllus pennsylvanicus, as they inhabit the same geographical area. However, the two species are easily distinguished through examination of life history, ovipositor and behavioural differences. Predators of G. veletis include American toads, wild turkeys, red-tailed hawks, wolf spiders and red-backed salamanders.
Crickets are orthopteran insects which are related to bush crickets, and, more distantly, to grasshoppers. In older literature, such as Imms, "crickets" were placed at the family level, but contemporary authorities including Otte now place them in the superfamily Grylloidea. The word has been used in combination to describe more distantly related taxa in the suborder Ensifera, such as king crickets and mole crickets.
Gryllus is a genus of field cricket. Members of the genus are typically 15–31 mm long and darkly coloured. The type species is Gryllus campestris L.: the European field cricket.
Platygryllus is a genus of crickets in the subfamily Gryllinae. Records of species distribution include Africa, southern Europe and in Asia: India, Java and the Philippines.
Gryllus rubens, commonly known as the southeastern field cricket, is one of many cricket species known as a field cricket. It occurs throughout most of the Southeastern United States. Its northern range spans from southern Delaware to the extreme southeastern corner of Kansas, with a southern range stretching from Florida to eastern Texas.
Gryllus bryanti is a species of cricket in the subfamily Gryllinae. G. bryanti lives on islands in the Caribbean Sea, including Eleuthera Island and Andros Island in the Bahamas.
An illegitimate receiver is an organism that intercepts another organism's signal, despite not being the signaler's intended target. In animal communication, a signal is any transfer of information from one organism to another, including visual, olfactory, and auditory signals. If the illegitimate receiver's interception of the signal is a means of finding prey, the interception is typically a fitness detriment to either the signaler or the organism meant to legitimately receive the signal, but it is a fitness advantage to the illegitimate receiver because it provides energy in the form of food. Illegitimate receivers can have important effects on the evolution of communication behaviors.
Gryllus assimilis, commonly known as the Jamaican field cricket and sometimes referred to as the silent cricket among other names, is one of many cricket species known as a field cricket. Its natural habitats are the West Indies and parts of the southern United States, Mexico, and South America, though as a result of widespread breeding programs to supply feeder insects to the pet industry since 2010, it has become available commercially throughout North America and Europe.
Gryllus firmus, commonly known as the sand field cricket, is a species of cricket in the subfamily Gryllinae. It is found in the southeastern United States.
Phyllopalpus pulchellus, known generally as the red headed bush cricket,handsome trig or handsome bush cricket, is a species of winged bush cricket in the family Gryllidae. It is found in Eastern United States.
Acanthogryllus fortipes, or the brown cricket, is a species of cricket from southern Africa. It is mostly dark brown in colour and has a large head. It is a common species in short grass, including artificial habitats such as lawns and fields.
