The following photos show a Great Spreadwing damselfly (Archilestes grandis) spotted on 08 October 2015, two days after the first Great Spreadwing was observed at a small permanent pond in a remote location at Huntley Meadows Park (HMP). This individual is a male, nicknamed “Mr. Magoo” because of the prominent dark spots in his eyes.
I’m not sure what “Mr. Magoo” was doing in the preceding photo. A novice odonate hunter might be fooled into thinking the damselfly is a female, ovipositing in the grass stem (endophytic oviposition). I speculate the young male was “test-driving” his terminal appendages, with the grass stem serving as a simulation of the neck of a female.
After two seasons of field observation of Great Spreadwing damselflies, I have noticed several males flexing their abdomen like gymnasts. Are they simply stretching, or is this behavior related to a pre-/post-mating ritual? It’s impossible to know for certain, but I’m sure it’s amusing to watch! In particular, notice the unusual “two-step dance” performed by the male featured in the following video.

I’m a fairly accomplished photographer, he said, not too modestly. In contrast, my skills as a videographer are relatively rudimentary as evidenced by the preceding video. My movies usually turn out better when I plan the shoot and use a tripod; in this case, the video clips were shot spontaneously (therefore hand-held) when an opportunity presented itself.
One of my mantras of wildlife photography/videography is “get a shot, any shot; refine the shot.” I wish the preceding video had turned out better. Although I was able to shoot a couple of video clips of this unusual gymnastic routine, there was no opportunity to refine the shots. Oh well, maybe next year!
Editor’s Note: According to Ed Lam, author and illustrator of Damselflies of the Northeast, the damselfly featured in the video is grooming itself.
He appears to be grooming in the video. They can’t reach down to knock off debris, spiderwebs, etc. but they can rub their legs together or against an object. Similarly, the abdomen seems to be contacting the wings. Sometimes you see this behavior after they have been handled and released if they don’t immediately fly away.
