Behaviour:
The grasshopper Ch. bornhalmi sings in an up and down waving manner using its hind legs, producing long ver- ses of 4–5 s duration. The two-leg system further allows for complex rhythmic patterns, because the legs can be used independently on the opposite sides of the body. Males of Ch. bornhalmi produce songs with rising sound amplitude levels over time, along with a ramp-shaped increase of the frequency range over the first second of the verse. The sound energy is radiated in the frequencies between 5 and 30 kHz, with most energy in the sonic range (Fig. 4). [1]
