The circadian calling activity of a lebinthine cricket with high-frequency calls is unaffected by cicada choruses in the day.

Background: Many factors can influence circadian rhythms in animals. For acoustically communicating species, both abiotic cues (such as light and temperature) and biotic cues (such as the activity of other animals), can influence the timing of signalling activity. Here we compare the 24-h singing activity of the cricket in the laboratory and field to assess whether the presence of other singing insects influences circadian rhythm.
