Abstract Signals are important for communication and mating, while they can benefit an individual, also be costly dangerous. Male field crickets call in order to attract female crickets, but gravid females of a parasitoid fly species, Ormia ochracea , attracted the use it pinpoint male cricket hosts. Conspicuousness vary with frequency, amplitude, temporal features. Previous work this system has only considered variation calls, both large scale, that is, amount calling at what time evening,...
Abstract Divergence in mating signals typically accompanies speciation. We examine two ecologically divergent sibling species of crickets to assess the degree and timing evolution prezygotic reproductive isolation. Gryllus saxatilis occurs rocky habitats throughout western North America with long-winged individuals capable long-distance dispersal; navajo is endemic red-rock sandstone areas south-eastern Utah north-eastern Arizona has short-winged only limited dispersal.
