The timing of calling,movement, and mating in the field crickets Gryllus veletis,G. pennsylvanicus,and G. integer

Summary The temporal relationships between mating, calling, and movement were studied in natural habitats at different densities in the field crickets, Gryllus veletis, G. pennsylvanicus and G. integer. There was variation between and within species, but males generally showed increased calling at dawn followed by a decline during the day. Matings were also more frequent at sunrise in most observations, and male and female movement declined near dawn. Female movement and sexual receptivity are closely related to levels of male calling and movement.
