I'm going to stick my head out of the trench here and say that this is a Southern Hawker. And if it is, he must be lost!! Cumbria has never been called a southern county!
I'm disappointed that I couldn't get his wings to show up any more clearly, but he was big, maybe 10cms in length!
@phil_howcroft Cheers Phil. I tried several angles to try to make the wings more visible. I was frightened to use flash, that would have been the final shot !!
