Bioacoustics. Males produce a soft song (at least for the human ear) by tegmino–tegminal stridulation, consisting of a long sequence of syllables (Fig. 4 a–d, i–l; table 2). A syllable is formed of a compact series of 80– 125 impulses, lasting for about 250–443 ms (up to 600 ms in recordings from Roesti & Keist 2009), followed after 41–183 ms by one (rarely 2–7) after–clicks (n=200 syllables from 9 males). The relatively short syllables recorded in the song of some males from Jeseníky Mountains (N Morava) may be the effect of the high temperature (30°C) during recording (Kočárek 2005). The impulse interval is highly variable, 2–9 ms. The following syllable begins after 58–297 ms. During pair formation, females may respond acoustically to males with simple clicks (Heller 1990). Spectrographic sound analysis reveals frequencies between 20–40 kHz (Fig. 4 q).
