Dragonfly Obelisk Posture

The dragonflies are swarming my neighborhood this week.

Dragonflies are fun to watch because they often return to the same perch over and over, giving you the opportunity to observe them closely.

Watch the abdomen on this one.

It has tipped its abdomen up into what is called the “obelisk posture.”

It is possible that it saw my camera as a threat and this was a defensive move. On the other hand, it was a hot day and scientists have suggested the obelisk posture is a way dragonflies adjust their exposure to sunlight and keep from overheating.

Cool!

Bug of the Week: Dragonfly Names

Dragonflies have such delightful common names.

If you have ever seen dragonflies flying over a pond, you know why many have the common name “skimmer.”

flame-skimmerTake the flame skimmer, so called because the mature males have a orange to red head and abdomen. This newly-emerged male hasn’t developed his full coloration yet.

roseate-skimmer-back-closeThe male roseate skimmer has a magenta or purplish hue.

Other dragonflies named for their colors include the Mexican amberwings, which are smaller than flame skimmers.

The name darner seems appropriate, given their long, slender body.

Take this common and widespread species, the green darner.

Here’s a list of other whimsical dragonfly names:

  • pondhawk
  • meadowhawk
  • dasher
  • glider

How about the black-winged dragonlet at the Arizona Dragonflies website?

Bug of the Week: Amberwing Dragonfly Posing

Two years ago I caught a Mexican Amberwing dragonfly hovering over the water. I have wanted to get a photograph of one sitting still ever since.

I finally had a chance. It was perching at the top of a red bird of paradise.

It is a pretty small dragonfly, although there isn’t much here to give it scale.

Dragonflies are interesting because they vary a lot in color. Some amberwings have completely brown-gold wings whereas others have patches in clear wings like this one. Makes dragonfly identification quite tricky at times.

Arizona Dragonflies has a lovely series of photographs of Mexican amberwing dragonflies that show the variation in wing color.

It always amazes me to see dragonflies flying miles from water in the desert. It just goes to show how strong fliers they are.

This one was perching and then catching flying insects as they flew by.

Have you spotted any dragonflies this week?
