looks like a variable to me. dainty i have seen in france dont have the same pattern on the tail end as your damsel. Variable does extend to this type of pattern as well- although this does look very dark.
where did you see them?
It was just the one I saw, amongst large reds and blue tailed etc at Upton Fen. I thought it might just be a variable but the 'Pi' type marking in the tail is similar to that shown on female dainty in Richard Lewingtons illustrations in Dragons of Britain and Europe.
