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