The 10 species of British ‘bush crickets’ (family Tettigonidae) are mainly restricted to southern England, whilst the 4 species of the distinctively different ‘crickets’ (family Gryllidae) are “increasingly rare and only likely to be found in the extreme South of England” (Tilling, 1987). It is the bush crickets that favour the night for their characteristic ‘songs’ or stridulation, raising their wings and rubbing them together. Last week the late summer burst of warmth seem to invigorate the local crickets and I managed to capture one (see image), a Dark Bush Cricket (Pholidoptera griseoaptera). This is a sturdy looking species, dark brown with a yellow underside and almost wingless, often occurring in bramble thickets and hedges, found close to our new garden. The song is a brief, penetrating chip (see You Tube clip at http://www.youtube.com/watch?v=D-5c8TUwva0), but a combination of the species occurring in numbers and the sound carrying well can make for an impressive chorus (Haes & Harding, 1997).
Roll on next summer!
