Oecanthus Capensis

	Oecanthus Capensis ''Oecanthus capensis'', the Cape thermometer cricket, is a species of tree cricket (Subfamily Oecanthinae). It has been found that the rate at which these crickets chirp follows Dolbear's law Dolbear's law states the relationship between the air temperature and the rate at which crickets chirp. It was formulated by Amos Dolbear and published in 1897 in an article called "The Cricket as a Thermometer". Dolbear's observations on the rela .... Description Similar to ''Oecanthus pellucens'', but a little smaller; the wings shorter, elytra of the female slightly stronger, male elytra shorter. The female's ovipositor is nearly the length of elytra. Range Southern, eastern and central South Africa. Habitat Ecology Etymology Cape; capensis - after the Cape of Good Hope. Thermometer cricket - The rate at which these crickets chirp can be used to the estimate the temperature. Taxonomy References Insects described in 1878 capensis {{Gryllidae-stub ...

picture info	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]
picture info	Tree Cricket Tree crickets are insects of the Order (biology), order Orthoptera. These cricket (insect), crickets are in the subfamily Oecanthinae of the Family (biology), family Gryllidae. Description Tree crickets as well as most other crickets have two pairs of wings. The fore wings are located closer to the head and are hard and leathery in appearance. The hind wings are located aft of the fore wings and are the wings it uses for flight. When the cricket is not in flight the fore wings fold back to cover the hind wings. The bodies of tree crickets are long and skinny with a coloration that matches their habitat. They have large powerful legs used for jumping. Their heads contain two antennae which can sense both touch and odor and compound eyes which are inherent in all Orthoptera. Distribution and habitat They live in trees and shrubs, for which they are well camouflaged. These crickets are nocturnal and can be found on every continent except Antarctica. In Europe, tree crickets hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Dolbear's Law Dolbear's law states the relationship between the air temperature and the rate at which crickets chirp. It was formulated by Amos Dolbear and published in 1897 in an article called "The Cricket as a Thermometer". Dolbear's observations on the relation between chirp rate and temperature were preceded by an 1881 report by Margarette W. Brooks,According to Frings and Frings, this is: Margarette W. Brooks, "Influence of temperature on the chirp of the cricket", ''Popular Science Monthly'' 20 (1881), p. 268; citing "W.G.B.", a writer whom Brooks does not further identify. although this paper went unnoticed until after Dolbear's publication. Dolbear did not specify the species of cricket which he observed, although subsequent researchers assumed it to be the snowy tree cricket, "''Oecanthus niveus''". However, the snowy tree cricket was misidentified as ''O. niveus'' in early reports and the correct scientific name for this species is '' Oecanthus fultoni''. The chirping of the more ...

picture info	Insects Described In 1878 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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
