Same answer as the other image
in that it is a female Ischnura and tough to say which one. On this one we seem to see more white on the side of the thorax and so would lean toward Ischnura posita, but it will be interesting to see what others think. Were these both taken in the same place? Were there any males or young females around?

Same place
There were other damselflies around too. I don't have clear pictures. I have two blurry pictures of something with a green thorax and a bright blue tip on a dark abdomen.

That sounds more like verticalis.
Check out the males of Ischnura verticalis in the guide. No blue on the tip of I. posita.
