The song is very quiet (audible from about 1m) and is produced particularly at dusk. The individual sounds, which can be represented roughly as 'tsb', are produced at irregular intervals. [1]
The faint calling song of the male, produced mainly in the evening and at night, consists of isolated syllables, often separated by irreguular intervals but sometimes repeated more regularly at intervals of about 1-4s. Occasionally, well-defined echemes are also produced, each composed of about 8-20 syllables repeated at the rate of about 6-10/s. Each syllable in such an echeme lasts for about 50-100ms, but isolated syllables are often shorter than 50ms. Heller (1998) has shown that Phaneroptera is most unusual among Tettigoniidae in producing sound only during the opening strokes of the fore wings, so that all the song components are opening hemisyllables.
