Black-tipped darner (Aeshna tuberculifera)
The genus Aeshna, or mosaic darners, contains many similar-looking species found in temperate and boreal regions across the Northern Hemisphere. If you live in the northern US or Canada, many of the large, fast dragonflies seen flying in swarms in late summer and fall belong to this genus.
A. tuberculifera is one of the largest Aeshna in North America, and in my opinion might be the coolest looking- just look at the turquoise on his thorax stripes!
