Nice photos! That last one is a damselfly. They are related to dragonflies, but only the damselfly can fold its wings over its body like that. And a dragonfly has such large eyes that they meet in the middle, but the damselflies have a gap between their eyes. I think of them as flying image processing machines. So much of their brain is devoted just to processing what comes in from their eyes.
Thank you, thats really interesting, didn't knew that!
