Mating damsel flies

We went for a  really super walk, at Valice, with my sister and her family. On the way (as well as getting absolutely plastered in mud!) we saw a lot of damselflies flitting above the stream.  I managed to catch this mating pair as they landed on a leaf about 12 feet away from us.   I think they are Demoiselle but am not sure whether they are Beautiful or Striped variety.  I suspect they are Beautiful Demoiselles.
There are a few extra pics in the extras, including of my sister and my new Nephew.
