Gryllus rubens
Southeastern field cricket
Gryllus rubens, the southeastern field cricket, is a trilling field cricket native to the southeastern United States. It is a cryptic sister species to G. texensis, from which it originated via peripatric speciation. The species exhibits remarkable phenotypic plasticity in its communication system, with male calling songs and female preferences shifting reversibly between spring and fall generations in response to temperature. Wing polymorphism is environmentally and genetically influenced, with long-winged morphs appearing in spring/summer and short-winged morphs predominating in autumn/winter.
