Gryllus integer
Western Trilling Cricket
Gryllus integer, the western trilling cricket, is a field cricket species distinguished by its nearly continuous trilling song rather than discrete chirps. It occurs in the western United States, where males produce species-specific calling songs to attract females. The species has been extensively studied for its behavioral ecology, including alternative mating tactics, personality traits, and antipredator responses. Populations show geographic variation in song structure, with some California males producing chirped songs rather than continuous trills.
