Sphecius speciosus, Eastern Cicada Killers, have an annual lifecycle. Males emerge first from last year's nests. They begin taking up position, monitoring and cruising over the nest site, watching for the emergence of the queens. They defend their territory from other males, as observed in this video.

Mating is quick. I was fortunate to be able to observe it twice in 2014. It takes, at most, 20 seconds.
