Visitor at rehearsal

During our choir rehearsal weekend we had several flying visitors. A bat flying around in the room on Friday evening and on Saturday this butterfly (too far away to get a better shot but like the little dreamy look of this one) and a huge dragonfly at least 10cm long who tried to get out again. We haven't seen any of them this morning during our last leg of the rehearsals so they must ether have found a way out or were hiding well.
