Natural History


Males spend much of their time in flight, patrolling lakeshores and river and stream edges, and catching prey and eating it while flying. They will sometimes join feeding swarms made up of several species of dragonflies. At night they often perch on tree trunks


Ponds, small lakes, slow rivers and streams. Often associated with sedges


Mating takes place near water. Female oviposits eggs one at a time in the stems of aquatic vegetation just above or just below the waterline
