Calling song/stridulation from a male Bog
Bush-cricket (Metrioptera brachyptera) in wet heath/bog with
Calluna vulgaris/Molina caerulea/Juncus
spp.
A quiet and soft, continuous ticking (5 audible elements/sec at 22°C) repeated
in long bursts. Very high pitched and only audible to
my ears at less than a five metre range.
