Gryllinae
Gryllinae, or field crickets, are a subfamily of insects in the order Orthoptera and the family Gryllidae. They hatch in spring, and the young crickets (called nymphs) eat and grow rapidly. They shed their skin (molt) eight or more times before they become adults. Field crickets eat a broad range of food: seeds, plants, or insects (dead or alive). They are known to feed on grasshopper eggs, pupae of Lepidoptera (moths and butterflies) and Diptera (flies). Occasionally they may rob spiders of their prey. Field crickets also eat grass. In the British Isles "field cricket" refers specifically to ''Gryllus campestris'', but the common name may also be used for '' G. assimilis'', '' G. bimaculatus'', '' G. firmus'', '' G. pennsylvanicus'', '' G. rubens'', and '' G. texensis'', along with other members of various genera including ''Acheta'', '' Gryllodes'', ''Gryllus'', and ''Teleogryllus''. ''Acheta domesticus'', the House cricket, and ''Gryllus bimaculatus'' are raised in captivity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gryllidae
The family ''Gryllidae'' contains the subfamilies and genera which entomologists now term true crickets. Having long, whip-like antennae, they belong to the Orthopteran suborder Ensifera, which has been greatly reduced in the last 100 years (''e.g.'' ImmsImms AD, rev. Richards OW & Davies RG (1970) ''A General Textbook of Entomology'' 9th Ed. Methuen 886 pp.): taxa such as the spider-crickets and allies, sword-tail crickets, wood or ground crickets and scaly crickets have been elevated to family level. The type genus is ''Gryllus'' and the first use of the family name "Gryllidae" was by Walker. They have a worldwide distribution (except Antarctica). The largest members of the family are the -long bull crickets (''Brachytrupes'') which excavate burrows a metre or more deep. The tree crickets (Oecanthinae) are delicate white or pale green insects with transparent fore wings, while the field crickets (Gryllinae) are robust brown or black insects. Subfamilies The family is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gryllus Firmus
''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. Description ''Gryllus firmus'' is very similar in appearance to other crickets found in the southeastern United States, the southeastern field cricket (''Gryllus rubens'') and the Texas field cricket (''Gryllus texensis''). It has a black head and prothorax, and a brown abdomen. It can be distinguished from these two species by the coloration and venation of the forewing, but more particularly, by its call. Males of this species chirp while males of the other two species trill. Distribution and habitat ''Gryllus firmus'' occurs in the coastal plain of the southeastern United States. Its range extends from Connecticut and New Hampshire to Florida and Texas. The long winged morph is migratory. It is replaced to the north and west of its range by the fall field cricket (''Gryllus pennsylvanicus''), and the two species hyb ...

Gryllus
''Gryllus'' is a genus of field cricket (Orthoptera, Gryllidae, Gryllinae). Members of the genus are typically 15–31 mm long and darkly coloured. The type species is ''Gryllus campestris'' L.: the European field cricket. Until the mid-1950s, native field crickets in eastern North America were all assigned to a single species, ''Acheta assimilis'' Fabricius. Although regional variation in calling song and life history were noted,Rehn, J.A.G., and Hebard, M. (1915). The genus ''Gryllus'' (Orthoptera) as found in America. ''Proc. Acad. Nat. Sci.

Gryllus Bimaculatus
''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. The species is popular for use as a food source for insectivorous animals like spiders and reptiles kept as pets or in zoos. They are easy to raise and do not require prolonged exposure to cold in order to complete their life cycle. Behavior Fighting In the wild, male crickets do not tolerate one another and will fight until there is a winner. The loser usually retreats without serious injury. The fighting method involves opening the mandibles as wide as possible, gripping the opponent's mandibles and pushing with the hind legs. Chirping Male crickets of this speci ...

Cricket (insect)
Crickets are orthopteran insects which are related to bush crickets, and, more distantly, to grasshoppers. In older literature, such as Imms,Imms AD, rev. Richards OW & Davies RG (1970) ''A General Textbook of Entomology'' 9th Ed. Methuen 886 pp. "crickets" were placed at the family level (''i.e.'' Gryllidae), 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. Crickets have mainly cylindrically-shaped bodies, round heads, and long antennae. Behind the head is a smooth, robust pronotum. The abdomen ends in a pair of long cerci; females have a long, cylindrical ovipositor. Diagnostic features include legs with 3-segmented tarsi; as with many Orthoptera, the hind legs have enlarged femora, providing power for jumping. The front wings are adapted as tough, leathery elytra, and some crickets ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acheta Domesticus
''Acheta domesticus'', commonly called the house cricket, is a cricket most likely native to Southwestern Asia, but between 1950 and 2000 it became the standard feeder insect for the pet and research industries and spread worldwide. They can be kept as pets themselves, as this has been the case in China and Japan. Description The house cricket is typically gray or brownish in color, growing to in length. Males and females look similar, but females will have a needle from the rear, around long. The ovipositor is brown-black, and is surrounded by two appendages. On males, the cerci are also more prominent and house crickets are also omnivores. Diet The house cricket is an omnivore that eats a range of plant and animal matter. Crickets in the wild consume flowers, seeds, leaves, fruits, grasses and other insects (including dead members of their own species). Crickets in captivity will accept fruits (e.g. apples, oranges, bananas), vegetables (e.g. potatoes, carrots, squash ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cercus
Cerci (singular cercus) are paired appendages on the rear-most segments of many arthropods, including insects and symphylans. Many forms of cerci serve as sensory organs, but some serve as pinching weapons or as organs of copulation. In many insects, they simply may be functionless vestigial structures. In basal arthropods, such as silverfish, the cerci originate from the eleventh abdominal segment. As segment eleven is reduced or absent in the majority of arthropods, in such cases, the cerci emerge from the tenth abdominal segment. It is not clear that other structures so named are homologous. In the Symphyla they are associated with spinnerets. Morphology and functions Most cerci are segmented and jointed, or filiform (threadlike), but some take very different forms. Some Diplura, in particular ''Japyx'' species, have large, stout forcipate (pincer-like) cerci that they use in capturing their prey. The Dermaptera, or earwigs, are well known for the forcipate cerci that most o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
