Oscillograms of calling songs of Chorthippus miramae from Orenburg region A, West-Kazakhstan region C and Buryatia D,E. Song recordings are presented at three different speeds (faster oscillograms of the indicated parts of the songs shown in F–J. At small scales (A–D) the maritimus-like echemes can be distinguished from the brunneus-like echemes by the higher amplitude. In all oscillograms the two upper lines are recordings of hind leg movements and the lower line is the sound recording. The ambient temperature near a singing male was 34 – 35 °C in (A,E) and 29 – 31°C in other cases.
