A Dragonfly Story



Blue Dasher
I had either no or almost no experience with dragonflies when I started at the nature center.  I found that one can not be there long before dragonflies cross your path.  They are on the wing from June until November and they made good targets for my camera.

This story is not about a species but a family.  They all have two sets of wings and fly, some better than others.  Some even migrate south in the autumn.

Common Whitetail
The mature dragonfly is the one that propagates the family.

Green Darner Pair
The male has a grasp of her "neck" and they fly around while she lays eggs in the water.  The female oviposits without the male ocassionally.

Dragonfly Larva
The eggs hatch in the water and a larva forms.  It goes through different stages in the water called instars.  Finally the larva is ready for the final moult and exits the water.

Dragonfly Exuvia
The larva climbs a reed until it is ready to exit its exoskelton.

Green Darner
 The newly moulted insect stays with the exuvia while its body pumps fluid into the wings.  When its body is ready it flies away to its new life.
