I've been going around our meadow by the brook now and again with the bat detector on auto-id, always finding lots of pipistrelles and smaller numbers of several other species, even a couple of Bechstein's if the auto-id is to be believed. Then in late July the detector was flooded with a continuous wooshing sound that confused its auto-id software. We hadn't much idea what might be making this racket as it's just about everywhere in our 3 acre plot. Then an article in a wildlife magazine about bush crickets gave us a hint - they tend to start singing, day and night, in late July. So we went down to the meadow in daylight using the bat detector to show us a place where the chuffing sound was loudest, and almost immediately my wife spotted this in a rough patch:- I think it's a long-winged conehead, and there must be a lot of them - I wonder if their noise interferes with the bats' hunting as well as with our bat-detecting?
