[QUOTE="RoyW, post: 1354640, member: 71737"] Hi all, Apologies for re-opening an old thread but I reckon this one deserves further discussion (even though the dragonfly season is now over in Britain!). I'm with Steve Clifton on this one - the photographs aren't especially clear, but I would say this is more likely to be an over-mature Common Darter than a Ruddy. Steve Dudley is definately over simplifying the seperation of the two species by giving the sides of the thorax so much weight (no time now but I will post a few photos to illustrate this tomorrow morning). One feature that is visible that points away from Ruddy for me is the colour of the frons ('face' for anyone who isn't into dragons' as much) - in a mature male Ruddy this is red, the same colour as the body. In these photographs the frons is a pale brown colour, other features have already been mentioned in previous posts. Regards, Roy. [/QUOTE]
