One evening, just after dark, the nymph will move entirely out of the water, clinging to a rush or cattail. It will take a few hours for the darner's wings to dry out enough for its maiden flight. Recently, researchers have been investigating the phenomenon of dragonfly migration. Dragonflies, including the common green darner, have been seen in spectacular mass flights. In some cases, the dragonfly was move more or less together in loose clusters.
Some scientists note the striking parallels between bird and dragonfly migrations.
They believe that factors of time, weather and geography may affect migration patterns of both creatures in similar ways. Still, bird migrations are true cycles in which each individual completes one or more round-trips during its lifetime. When dragonflies migrate, it's a one-way trip. The dragonfly's offspring will have to make the return leg of the journey during the next season.
