At first I thought it was the Black-tailed Skimmer as I couldn't see any yellow edging on the side of the body that I would expect to see with a Broad-bodied Chaser and I didn't think it was quite fat enough.
I have seen some images of a Black-tailed Skimmer that didn't have very much black on the tail end also, so confused as ever. However I have been advised by Simon (see Comments section) that it is indeed a Broad-bodied Chaser.
Since then my learned friend John from Hedgeland Tails http://hedgelandtales.blogspot.co.uk
(see comments section) has I believe, correctly identified the species as a Scarce Chaser (Libellula fulva)
