Pachydiplax longipennis
Blue Dasher
The Blue Dasher (Pachydiplax longipennis) is a common and widely distributed dragonfly in the skimmer family Libellulidae. It is the sole species in its genus. Adults are characterized by a blue pruinose abdomen, particularly in males, and are known as "perchers" that hunt from stationary positions. Males exhibit pronounced territorial behavior at breeding and feeding sites, with social dominance hierarchies influencing dispersal patterns. The species occurs throughout North America and into the Caribbean.
