David Weissman is currently revising the species of Gryllus from the western and central United States. That study will describe the song, morphology, life cycle, and geographical and ecological distribution of G. vocalis in relation to the many other western species.
More information: subfamily Gryllinae, genus Gryllus
Song at 25°C: Weissman et al. (1980) described the song as having 2 to 3 pulses per chirp produced at a rate of 25 to 42 per sec and averaging 220 chirps per minute at 25°C.
