The house cricket is known for producing a loud, continuous chirp at night, while the chirp of the field cricket is less high-pitched but occurs both day and night. Chirp rates also vary by species and temperature. However, problems with putting this theory into practice abound. Pulse rate and the pattern of the pulses also differ between cricket species.
