Natural History


Males make long patrol flights along the shore or out over the open water usually traveling almost the same path. Royal River Cruisers can be found hanging vertically in trees near the water. They can also sometimes be found joining with other species of dragonflies in feeding swarms, particularly later in the day


Large rivers, streams, and lakes. Often found in slower moving bodies of water than other Cruisers. In Minnesota they have only been found around the Mississippi River in the southeast corner of the state


Mating occurs in the tree tops. Egg laying usually happens in the afternoon and can be done by tapping the water's surface during quick flights or may be done more leisurely, spending up to a couple of minutes in a small area.
