I suppose I was hoping to have identified relatively rare species of these, but as their names suggest, they are both ‘common’! Nevertheless it was great to have had that extra moment to focus on these before they flew away.
For a comprehensive list of dragonflies, please see the British Dragonfly Society webpage.

Great pictures! I’m not sure, but I think the red one is a Ruddy Darter, not a Common Darter. The Common Darter have yellow stripes on its legs, and the Ruddy Darter have all-black legs.
Thanks! They all looked similar to me when I pored through the species list :). I shall take another closer look and change the description.
