Platygryllus Sudanus
''Platygryllus'' is a genus of crickets in the subfamily Gryllinae. Records of species distribution (probably incomplete) include Africa, southern Europe and in Asia: India, Java and the Philippines. Mating behaviour Males of this genus transfer sperm to the female via a spermatophore which is externally attached to a females ovipositor. Male ''P. supplicans'' guard females after spermatophore transfer to prevent the female from removing his spermatophore prematurely. The females of ''P. primiformis'' use premature spermatophore removal as a form of cryptic female choice leaving larger males' spermatophores attached for significantly longer than smaller males.Bateman, P.

Chopard
Le Petit-Fils de L.-U. Chopard & Cie S.A., commonly known as Chopard, is a Swiss manufacturer and retailer of luxury watches, jewellery and accessories. Founded in 1860 by Louis-Ulysse Chopard in Sonvilier, Switzerland, Chopard has been owned by the Scheufele family of Germany since 1963. Chopard is best known for making high-quality Swiss watches and jewellery, and its clients have included Tsar Nicholas II of Russia. The company is headquartered in Geneva and has a site in Fleurier, Canton of Neuchâtel, that manufactures watch movements. History Early history The company founder, Louis-Ulysse Chopard, was a Swiss watchmaker who grew up in Sonvilier, a town in Swiss Jura. In 1860, he established his L.U.C. manufacturing company in Sonvilier, having observed that it was more profitable to market the finished watch than to just make the mechanical movement. After Louis-Ulysse's death in 1915, the company was taken over by his son Paul-Louis and grandson Paul-André. The com ... [...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.

''Platygryllus primiformis'' is a small (approx. ) brown cricket and is a member of the true cricket family Gryllidae. Location This cricket is found in Eastern and Southern Africa. Uses This cricket has been used as a study species in behavioural ecology, specifically mate choice Mate choice is one of the primary mechanisms under which evolution can occur. It is characterized by a "selective response by animals to particular stimuli" which can be observed as behavior.Bateson, Paul Patrick Gordon. "Mate Choice." Mate Choic ....Bateman, P.
