American Rubyspots (Hetaerina americana) along the Little Miami River

...continued from the previous post (click here).

Flashy male and female American Rubyspot (Hetaerina americana) damselflies were even more abundant than the Powdered Dancers (Argia moesta) featured in the previous post. Everywhere I looked the striking red metallic males were either flying over the water or perching on water willow (Justicia americana), their telltale ruby red wing spots easily giving them away...

The red metallic thorax and head of the male American Rubyspot (Hetaerina americana) damselfly flashed in the early evening sun. I was videoing the damselflies that night instead of photographing them. I wish I had taken a few good photos so I could have gone back to study the detail of the yellowish-gold sutures and the yellow veining that shows in the gorgeous red wing patches. This photo was an accident. I toggled the video switch off without realizing it. Wish I had taken a few photos instead of just videos (but I wanted to capture their movements so I could watch them in the winter)!

Male American Rubyspot damselflies along the Little Miami River. It was so nice to just sit and watch these jewel-toned damselflies. The sun was still very warm and the cicadas very loud, their song racing through the river valley in waves...

Female American Rubyspots are just as charming as the males, but they shine with orange and green highlights instead of the deep ruby red.

I took these videos on July 30, 2011 between 7:00 and 7:45 p.m. along the Little Miami River in Warren County. This area of the Little Miami Trail near the powder factory is an excellent place to watch damselflies. It's easy to get down to the rocky banks there, and massive patches of water willow can be found...both of which attract these beautiful insects.

Powdered Dancers (Argia moesta)...at the powder factory!

The evening sun was warm and the humidity was high as I climbed down the old deer trail to get to the rocky bank along the Little Miami River near the abandoned Peter's Cartridge Factory. The area was thick with water willow (Justicia americana), and damselflies flitted among the rocks and vegetation while cicadas pounded out their ancient insect song...

A female blue form Powdered Dancer (Argia moesta) dances among rocks and branches hidden in a thick patch of water willow (Justicia americana) along the Little Miami River. At the end of the video you can see her eating prey.

(A few people have mentioned they can't see the video. If it's not showing up for you, click here to go directly to Vimeo to see it. It's not the most exciting video ever...but during winter, it's nice to hear the water and listen to the cicadas and think about the summer dragons and damsels ahead! :-)

Powdered Dancers get their common name from the pruinescence (powdery-looking coating) that forms on their bodies. Pruinescence (or pruinosity) appears on several type of odonates (mostly the males). It's usually powdery white, gray, or light blue. You may recognize the term as it relates to fruit--plums or grapes both develop a pruinose covering. A quick look in the glossary of "Dragonflies and Damselflies of the East," by Dennis Paulson, explains pruinosity as it relates to odonates...

"...powdery (actually waxy) bloom on odonates that exudes from cuticle and turns it light blue, gray, or white, deposited on mature individuals (more commonly males) of many species of odonates"

The Blue Dasher dragonfly in this post has the pruinose covering on its abdomen that's easy to see.

Thanks, to Mike of "Everybody Funny" for helping me identify this damselfly and for recommending the Paulson dragonfly and damselfly book. It's awesome.
