Cooled down, grey skies and dragonflies

It has cooled way down, and its overcast. Here's something scary: I just took this picture of a silver maple hanging over the edge of the Portage, and its leaves are already turning color.

There's a huge snag (dead oak), maybe 80 feet tall on the bank above the river, and when there's no wind, the dragonflies sit at the tips of the dead branches. Each tiny branch end has its own dragon. What are they doing up there? No water, no females, and birds can come by and eat them. Why do they do it?

Here's some arrowhead (Sagittaria) on the riverbank, but I missed the flowers. They aren't as thick as they were last year.
