Sonogram of Sickle-bearing Bush-cricket (Phaneroptera falcata) stridulation [sicklebearingbushcricket117986ecut1]

Wye NNR, Kent, England  18 September 2021

Calling song/stridulation from a male Sickle-bearing Bush-cricket (Phaneroptera falcata) in calcareous grassland on chalk downland at 22C.

A single, faint, largely ultrasonic element/syllable repeated every 1.2 to 1.8 seconds. Mostly inaudible to my ears, except at very close range with microphone right next the insect (much louder with bat detector set to 20 kHz). Long series lasting several minutes often preceded by an echeme of around 16 syllables at a rate of 8/sec (80-90 ms per syllable).
