Great day in the field – Roesel’s Bush-cricket

The sun came out this afternoon so I headed into the field in search of Roesel’s Bush-cricket – a species first recorded in Devon in 2014 which until now I have failed to find! Went to a couple of areas where it had been recorded before. I found a single adult in an uncut road verge on the south side of Rewe and then found three individuals by the food alleviation scheme in Exwick directly adjacent to to the north side of Station Road.

Roesel’s Bush-crickets are tricky to find but with the use of a bat detector (which makes their distinctive but inaudible songs audible) they can be tracked down. I use a Batbox Duet set at 40kHz and their songs then become audible.

Here is the current known (to me) distribution of Roesel’s Bush-cricket in Devon

And this is the classic habitat – rough uncut grassland

If you see or hear any Roesel’s Bush-crickets in Devon – please let me know – I’m the county Recorder for Orthoptera – email me: adrian dot colston at gmail dot com …. many thanks
