Ruddy Darter?

Another visit to the area we are planning an Orienteering event in. Very productive in terms of visiting possible control sites.

I only took my small camera. I could have done with my main camera and long lens to catch the Dragonflies and butterflies. Finally managed to get one as it settled. I think it is a Ruddy Darter. It could be a Common Darter but happy for anyone to help me with the identification.
