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. integer in relation to the many other western species.
Song at 25°C: Song in some populations consists of sequences of 3-pulse units produced at a rate of ca. 17 units per sec. (see upper spectrogram). The effect is a "stutter trill." In other populations sequences of single pulses and of pairs are the rule.
