At last we have had some proper summer evenings where I can get in the garden after work. Yesterday I spotted a Speckled Bush Cricket on the Heuchera.
Apparantly, naturalists armed with a bat detector are at a distinct advantage when searching for speckled bush crickets as the stridulation of the male can easily be heard with one up to 30 meters away. Males sing at a peak frequency of 40khz and the song is revealed as a short tick repeated regularly at intervals of four or five seconds.
I will whip our my bat detector tonight!
