Female Common Blue Damselfly

We went down to see D's mum and dad today and after lunch made our way to Chasewater Country Park to see if we could get a blip.

I spotted this damselfly which I identified as a female common blue damselfly. I remember blipping one of these before, on July 4th 2015 , but when I compare them they seem to be a bit different so it looks like one of them has been mis-identified.
