The species is best located by listening for its song. It has a very distinctive call which has been described as the sound emitted from under a high tension electricity pylon in the rain! However weather conditions need to be still and hot to hear the song. [1]
On sunny days the males sing in prolonged continuous bursts. Although the osng is high-pitched, like that of most bush crickets, it can be heard by most people as a distinctive 'buzz'. In most extensive grassland habitats the males are venly spaced out, and sing from perches. ... Where wind or rain has broken clusters of grass stems to form a rough 'platform', three or more males may compete to occupy the perch, often emitting short bursts of song as they move about, and briefly skirmishing on contact. [1]
The song is a soft, high-pitched, completely uniform buzz, which is only briefly interrupted at long intervals. In comparison with the harsh buzz of Tettigonia cantans, the M. roeselii song is distinctly softer and quieter, audible from only about 10m; nevertheless a whole meadow can be filled with its song.
