Paxton Pits Dragonflies

I wanted to get a good image of a flying Brown Hawker but failed dismally to get any in focus. I felt a bit of compensation with this image of a blue damselfly feeding off another insect - looks like a mayfly but not sure.
The trio of Blue Damselflies with their reflections also was surprisingly sharp.
Red Darters flying in tandem worked reasonably well but I prefer the pair in the tree with one coyly looking round a leaf.
Finally a Water Boatman - difficult to portray the fact that it is hanging on the underside of the water surface.
