One last try to see if we could pick up on some autumn swarming.

Last night some of the group trundled off to a local icehouse. Bob and Jonathan were dead tired having been out checking boxes all day. Chris Vine from the Cambridgeshire Bat Group  brought his harp trap and we out up a single mist net.  Pipistrelle activity was high all night. The wind fell and a Natterer’s  soon went into the harp trap. Later in the evening a brown long eared bat, a pipistrelle and a Daubenton flew into the net

What was quite interesting was that all the bats were juveniles who wouldn’t have been looking for a mate. Maybe they were sussing out potential hibernation sites. ( we regularly find bats here on hibernation surveys)
