Gryllus Texensis
''Gryllus texensis'' is a species of cricket described by William H. Cade and Otte in (2000). Cade and Otte clarify that field crickets collected in the Southeastern United States from Florida to Texas identified as ''Gryllus integer'', were in fact misidentified, and should have been classified as ''G. texensis''. Morphologically, Cade and Otte found no differences between ''G. texensis'' and ''Gryllus rubens ''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.

William H
William is a male given name of Germanic origin.Hanks, Hardcastle and Hodges, ''Oxford Dictionary of First Names'', Oxford University Press, 2nd edition, , p. 276. It became very popular in the English language after the Norman conquest of England in 1066,All Things William"Meaning & Origin of the Name"/ref> and remained so throughout the Middle Ages and into the modern era. It is sometimes abbreviated "Wm." Shortened familiar versions in English include Will, Wills, Willy, Willie, Bill, and Billy. A common Irish form is Liam. Scottish diminutives include Wull, Willie or Wullie (as in Oor Wullie or the play ''Douglas''). Female forms are Willa, Willemina, Wilma and Wilhelmina. Etymology William is related to the given name ''Wilhelm'' (cf. Proto-Germanic ᚹᛁᛚᛃᚨᚺᛖᛚᛗᚨᛉ, ''*Wiljahelmaz'' > German ''Wilhelm'' and Old Norse ᚢᛁᛚᛋᛅᚼᛅᛚᛘᛅᛋ, ''Vilhjálmr'').

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Southeastern United States
The Southeastern United States, also referred to as the American Southeast or simply the Southeast, is a geographical region of the United States. It is located broadly on the eastern portion of the southern United States and the southern portion of the eastern United States. It comprises at least a core of states on the lower East Coast of the United States and eastern Gulf Coast. Expansively, it reaches as far north as West Virginia and Maryland (bordered to north by the Ohio River and Mason–Dixon line), and stretching as far west as Arkansas and Louisiana. There is no official U.S. government definition of the region, though various agencies and departments use different definitions. Geography The U.S. Geological Survey considers the Southeast region to be the states of Alabama, Florida, Georgia, Arkansas, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, and Tennessee, plus Puerto Rico and the United States Virgin Islands. There is no official Census Bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Florida
Florida is a state located in the Southeastern region of the United States. Florida is bordered to the west by the Gulf of Mexico, to the northwest by Alabama, to the north by Georgia, to the east by the Bahamas and Atlantic Ocean, and to the south by the Straits of Florida and Cuba; it is the only state that borders both the Gulf of Mexico and the Atlantic Ocean. Spanning , Florida ranks 22nd in area among the 50 states, and with a population of over 21 million, it is the third-most populous. The state capital is Tallahassee, and the most populous city is Jacksonville. The Miami metropolitan area, with a population of almost 6.2 million, is the most populous urban area in Florida and the ninth-most populous in the United States; other urban conurbations with over one million people are Tampa Bay, Orlando, and Jacksonville.

Gryllus Integer
''Gryllus integer'', commonly known as the western trilling cricket, is one of many species of field cricket (subfamily Gryllinae) in the genus '' Gryllus''. It is called the "triller" field cricket because its song is nearly continuous rather than broken into discrete chirps. ''G. integer'' can be found in parts of the Western United States, having been recorded from Oregon, California, Arizona and New Mexico.Hedrick, A. 1986. Female preferences for male calling bout duration in a field cricket. Behav Ecol Sociobiol, 19, 73-77. Morphology ''Gryllus integer'' can be medium to large in size, ranging from 17.1- 24.0 mm, it is macropterous(large-winged), its head and pronotum are jet black and tegmina is light brown.Weissman, D. 1980.

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Gryllus Rubens
''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. Description Morphology ''Gryllus rubens'' has been found to be morphologically indistinguishable from '' G. texensis'', with which it shares its range. Compared to ''G. texensis'', female ''G. rubens'' are found to have longer ovipositors. It has been found that ''G. rubens'' has a peripatric origin derived from one lineage of geographically subdivided ancestor of ''G. texensis''. Wing morphology Many studies on ''G. rubens'' revolve around their ability to exhibit wing polymorphism. Many of which are done in northern Florida where ''G. rubens'' occurs year-round. In the spring/summer seasons, ''G. rubens'' is often found to have long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Insects Described In 2000
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] |
