Damselfly

We took a walk to see the Owl this morning and yes is is still there, but it looks a lot smaller than when I first saw it. I have never seen more than one and don't know if it is on its own or not. Anyway I spotted a few Damselfly while I was there and until 10 minutes ago I thought it was a Dragonfly but now know the difference between them....I think this is a Common Blue....If anyone knows different please let me know
