These beautiful dragonflies prefer to rest on stones rather than vegetation. The extent of the markings in the wings varies with the individual, but the males have more heavily marked wings. The wing color also deepens with age ranging from pale purple to black. On hot days, resting individuals can adopt an obelisk posture, pointing their abdomens towards the sun - when the sun is high they sometimes appear to be trying to stand on their heads. They do this in order to help regulate their body temperature.
