I also (of course!) had a mystery or two....
Here's the first one. It looks to be a female Aurora Damsel (Chromagrion conditum) but it is too late in the year by a couple of weeks (seen 21 July) and it doesn't have the usual spread-wing posture that this species is supposed to display.
The second isn't a very good picture, but you can get the pattern and the distinct orange coloration.
