Song: Weissman and Gray (2019) described the song as loud, with 11–17 pulses per chirp and usually <2 chirps per second.
Identification: A key to the adult males of native US Gryllus is in Weissman and Gray (2019).
DNA: See Gray, Weissman, et al. (2020).
Habitat: Human maintained lawns, golf courses, schools, and other such habitats as well as fresh and salt water marshes.
Life cycle: No diapausing stage, possibly making it easy to rear continuously for scientific or commercial purposes.
Season: Two to three generations per year, found year–round.
Name derivation: In reference to the high number of pulses per chirp.
