First Darners of Spring

One of the most common dragonflies in North America is the Common Green Darner. Green Darners are one of the migratory dragonflies of North America and masses of migrating dragonflies have been seen along the east and west coasts as well as along the coast lines of the Great Lakes. These darners were first seen 4-10-2015 at the Fox Island County Park Nature Center wetlands.
This Green Darner male has clasped the female just behind her head in the typical tandem position for odonata.  The male guards the female from competitive fertilization as she lays eggs on verticle and horizontal stems and twigs.
          Many times females will lay eggs solo like this darner laying eggs on a floating stem
