Dragons & Damsels

I found this stunning little creature last Friday.  At first I thought it was a black butterfly, and fumbled with my camera to get a picture of it before it fluttered away. Much to my surprise, when I got home and put the pictures on the computer, I saw that this was a dragonfly.  Or so I thought.

When I researched a black-winged dragonfly, I was let to understand that this ebony beauty was really a damselfly.  Isn't that a great name?!  I picture a beautiful lady with sparkling, flowing scarves and a wind-billowed, shimmering dress standing on a castle rampart with her hair streaming behind her.

So what is the difference between a dragonfly and a damselfly?

Well, the biggest difference that I think would help a person identify them in the field is the way they hold their wings at rest.  Both dragonflies and damselflies have two pairs of wings.  However, a dragonfly will rest with his two pairs outstretched, and a damselfly holds hers upright, like a butterfly at rest.  (Hency my mistaken initial identification.)

Here is a dragonfly (below).  You can see how his wings are outstretched as he rests on the stalk of grass.

The damselfly (in the first photo) is an ebony jewelwing, and what an apt name.  It is lovely and shiny.  This one picture is a male.  The bodies of the males are more of a metallic green, and the females are more brown.  Their scientific name is Calopteryx maculata.  Calopteryx is from the Greek, meaning beautiful wing.  Maculata refers to the white spot the females have on the tips of their wings.

The dragonfly (second photo) is a male widow skimmer.  The males have white coloring at mid-wing, whereas the females do not.  His scientific name is Libellula luctuosa.  I had a hard time finding the etymology of Libellula, but it may be related to the Latin word for booklet.  Luctuosa has reference to mourning, and may be related to the black coloring on both the male and female.
