The similarity with European
Leuchorrhinia struck me before I scrolled down - it soon became apparent why that was!
I'm certainly not going to question the species in your revised ID - but are you
sure that it's a female? It looks more like an immature male to me (judging by the appendages at the end of the abdomen)
Some great shots anyway (Spectres Blue Dashers included) - I look forward to seeing more of these of species that we don't get to see on this side of the Atlantic.

PS. I was going to post a couple of images of the earliest species that we see - it looks like they need to be uploaded to a website first and linked from there, is this correct?
