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