Natural History


Males swiftly patrol a territory, along river and stream banks or lake shores, of up to 100 yards, sometimes stopping to hover. Foraging often takes place in woodlands away from water with the cruiser flying low over the ground, weaving through the vegetation. When at rest they often hang vertically from twigs or leaves or lay horizontally on branches


Large slow moving streams and rivers with sandy bottoms and not much vegetation Also wave-swept lakes shores.


Mating can occur even before a cruiser is fully mature. Females lay eggs by flying over the water and quickly tapping the surface of the water with their abdomen
