Velarifictorus Micado
''Velarifictorus micado'', the Japanese burrowing cricket, is a cricket in the subfamily Gryllinae (family Gryllidae).bugguide.net ''Velarifictorus micado'' species information. It is found in southern Asia, along with an introduced population in the United States. It was first reported in the US in 1959, likely as overwintering eggs in the soil of imported plants, and has since spread all throughout the eastern half of the country.

Henri Louis Frédéric De Saussure
Henri Louis Frédéric de Saussure (; ; 27 November 1829 – 20 February 1905) was a Swiss mineralogist and entomologist specialising in studies of Hymenoptera and Orthopteroid insects. He also was a prolific taxonomist. Biography Saussure's elementary education was at Alphonse Briquet's then, as an adolescent, at the Hofwyl school run by Philipp Emanuel von Fellenberg. At the University of Geneva he was taught by François Jules Pictet de la Rive, who introduced him to entomology. After several years of study in Paris he received the degree of licentiate of the Faculty of Paris and obtained the degree of Doctor from the University of Giessen. He worked mainly on Hymenoptera and Orthoptera. His first paper, in 1852, was on solitary wasps. In 1854 he traveled to the West Indies, then to Mexico and the United States of America. There he met Louis Agassiz. He returned to Switzerland in 1856 with collections of American insects, myriapods, crustaceans, birds and ...

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.

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 i ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Orthoptera Of Asia
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. More than 20,000 species are distributed worldwide. The insects in the order have incomplete metamorphosis, and produce sound (known as a "stridulation") by rubbing their wings against each other or their legs, the wings or legs containing rows of corrugated bumps. The tympanum, or ear, is located in the front tibia in crickets, mole crickets, and bush crickets or katydids, and on the first abdominal segment in the grasshoppers and locusts. These organisms use vibrations to locate other individuals. Grasshoppers and other orthopterans are able to fold their wings (i.e. they are members of Neoptera). Etymology The name is derived from the Greek ὀρθός ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Insects Described In 1877
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
