Natural History


One of the few species in North America that migrate south. Many emerge in late summer and begin to migrate south in large groups. When they arrive at their southern destination they mate and lay eggs. Their offspring grow as nymphs and when they emerge they fly north, arriving and laying eggs before most other species emerge. The offspring of these darners start the process over again. Common Green Darners that do not emerge in time to migrate will mate and lay eggs in their northern territory. Their offspring will over winter as nymphs similar to other species of dragonflies that do not migrate.


Still waters such as lakes, ponds, marshes and slow moving streams


Pairs lay eggs in water logged wood or aquatic vegetation while in tandem
