The Heart of a Damsel

I'm struggling with ID again......I believe it's a Scarce Blue-Tailed Damselfly because it has the solid black body and of course, a blue tail ;-)) but I really can't be sure as I've never seen one before :-/

I found this on a nice stroll round the gravel pits, even though I was actually looking for dragons, without much success, as I think is was a bit too overcast and windy for them. It has turned into a beautiful day now......lets hope it stays like that for the long weekend :-))
