Cyphoderris Strepitans (Orthoptera: Haglidae): Reproductive Biology and Geographical Distribution

Biology and Reproductive Behaviour of Cyphoderris strepitans

Coping with the cold: temperature and mating activity of male sagebrush crickets Cyphoderris strepitans (Orthoptera: Haglidae)

The effect of temperature on male sexual displays is well documented but its role in mediating the differential mating success of males is less well established. Male sagebrush crickets Cyphoderris strepitans Morris and Gwynne occur in high-elevation sagebrush meadows in mountainous areas of the western U.S.A., and often are observed singing at temperatures as low −8 to −4 °C to attract sexuall...

Multivariate sexual selection on male song structure in wild populations of sagebrush crickets, Cyphoderris strepitans (Orthoptera: Haglidae)

While a number of studies have measured multivariate sexual selection acting on sexual signals in wild populations, few have confirmed these findings with experimental manipulation. Sagebrush crickets are ideally suited to such investigations because mating imposes an unambiguous phenotypic marker on males arising from nuptial feeding by females. We quantified sexual selection operating on male...

During the Mesozoic Era there flourished a group of species of saltatorial Orthoptera of the suborder Ensifera that are included in the fBmily Haglidae, of which fossils representing more than 30 genera are known. T h e Haglidae comprise the subfamilies Elaglinae, Isfaropterinae, Cyrtophyllitinae, and Prophalangopsinae. During the upper Jurassic, according to Sharov (1971), species of the last-...

Functional morphology of tegmina-based stridulation in the relict species Cyphoderris monstrosa (Orthoptera: Ensifera: Prophalangopsidae).

Male grigs, bush crickets and crickets produce mating calls by tegminal stridulation: the scraping together of modified forewings functioning as sound generators. Bush crickets (Tettigoniidae) and crickets (Gryllinae) diverged some 240 million years ago, with each lineage developing unique characteristics in wing morphology and the associated mechanics of stridulation. The grigs (Prophalangopsi...
