Forewings

Damselfly or Dragonfly?

6-16-16  damselfy & dragonfly 178A visit to a pond will usually include sightings of dragonflies and the more delicate damselflies.  Both of these types of insects are in the order Odonata (Greek for “tooth,” referring to the serrated jaws of the adults).  They are separated into two suborders, due to their wing shapes and sizes. The wings of dragonflies differ in shape and size (hind wings are broader than forewings), whereas damselfly fore and hind wings are similar in shape, with the hind wings sometimes being smaller.

In addition to wing differences, damselflies have eyes that are separated by more than an eye’s width, whereas dragonfly eyes either touch or are separated by less than an eye’s width.  Damselflies are smaller and more slender than dragonflies and perch with their wings closed over their abdomens or held slightly spread.  Dragonflies at rest hold their wings out flat or downward.  In addition, dragonflies are more powerful and acrobatic in flight than damselflies.

Although these differences distinguish them, damselflies and dragonflies do have many similarities. Both are carnivorous, both spend most of their lives as aquatic larvae, and both lay their eggs in or near water.
