Odonata

Iowa's dragonflies and damselflies, order Odonata, are fairly well studied, at least recently.  In fact, there is a great web site that deals with them, found at www.iowaodes.comThe Iowa list contains 109 species.

Dragonflies and damselflies are very watchable insects.  They are every bit as entertaining as the butterflies.  In addition, they are important predators of other insects, in particular some of the pest species like mosquitoes.

In fact, the aquatic larval forms of dragonflies and damselflies are important predators as well.  Since mosquito larvae are aquatic organisms as well, they are prey in both stages.

Some things are just being learned about dragonflies and damselflies.  For example, some are migratory in a manner that is similar to monarch butterflies.

The photo on the right is of a blue dasher, Pachydiplax longipennis.  It has some parasitic mites on its abdomen--the bright red dots. 

On the left is the Halloween pennant, Celithemis eponia. Both species are fairly common in Iowa.
