A huge fat bumble bee flew in through the kitchen window. Species unknown but not one of the usual white-tailed ones; it had a black, conical tail. So large I could still hear it buzzing quite clearly once I'd got it outside and shut the (double-glazed) window. It must have been attracted by the daffodils on the window sill, right? No, it was buzzing around and clinging to my trouser leg. And once I'd got it outside it spent some time investigating my bike, specifically the rear rack, which was standing by the door.
