Found this "not so little" beast flying round my garden shed today. A lower pitched "buzz" than a typical bee - it sounded a bit like a very small motorbike engine! I presume it's some sort of beetle. The wingspan was at least 2 inches. The first picture is after it crashed into the window - and presumably a bit disoriented, considering the "thwack" when it hit the glass. (As you can see my garden shed is not going to win any competitions for being clean and tidy!) The second picture is after it was dead - it took several goes to squish it. I judged that anything that big, and color coded orange and black, was a bit risky to deal with trying to get a good picture while it was still alive. FYI the UK 50p piece for size comparison is 27.3mm (1.075in) diameter.
