We took the bat detector for a walk down the lane near T's in Felixstowe at about 9pm on Friday evening. Picked up the sound of a couple of Noctules and a few Pipistrelles, but were amazed to hear loads of crickets in the hedges and bushes. When I turned the detector off I could still just hear them, very high pitched, way beyond T's hearing. After some research on-line I decided they were Dark bush-crickets, and later remembered that I saw one last autumn in his bathroom.
When I first moved to Swaffham they were quite numerous in my garden which was thoroughly overgrown, but I am afraid I only see the occasional one now since I have tidied it up.
