Black Setwing - Dythemis nigrescens - male

Black Setwing - Dythemis nigrescens - Male
San Antonio area, Bexar County, Texas, USA
September 4, 2006
This was one of two males hanging around a female in the same area all afternoon. She seemed receptive to both males, but I never witnessed a *hook-up* by either of them.

This photo was the posture he would take each time he would perch after making a pass at her, or a brief confrontation with the other male. The female would also take the same posture. Here is one of the photos I took of her during the same time.

So how was the weather?
When it's hot, dragons can be seen in an obelisking posture, with rear end elevated and, that way, less area exposed to the sun. The ones I've seen do this - different species than yours - typically have a bit of curl to the body, so the thorax is almost level with the ground while the abdomen heads upwards.

Or maybe this is some sort of macho dragonfly push-ups. (I know, the female did it too.)

 
Made in the shade . . .
Actually it was fairly warm that day, but not as hot as it had been most of the summer here. I don't know the exact temp, but it was in the 90s for sure. Where it had been in the low 100s just a few weeks before. However, when and where these photos were taken was a nice shadey area, so I think the posturing was more of body language of some sort.

What it appeared to me was more of a flirting type action than anything to do with the weather. But again I'm pretty new to all this, so that was just my guess. It just seemed like the female was signaling to the males that she was ready to ummm . . . *dance* with one of them.

I hung around for a good while hoping to get some photos of a couple paired together, but never got that oppertunity. Maybe next time?

 
They are hard to figure out.
Last year, I saw one Mexican Amberwing, a tiny orangish dragonfly. Now, they're all over the place. Today, a male and a female were flying around the end of a hollowed-out branch about 4 inches in diameter and sitting on the water. I couldn't figure out what was up, as they made no contact. They kept it up for several minutes, went away, then returned for more of the same.

 
Interesting . . .
I don't guess I've seen any Mexican Amberwings yet . . . now I'll have to look them up so I can keep a look out since I'm pretty close to Mexico.

I agree they're tough to understand at times, but fun to watch for sure. Being fairly new to this "hobby" I'm learning more every time I go out looking for dragons. It's been helpful for me to have some things growing in my back yard that seem to attract things they like to eat. And when there aren't any close by, I've got 6 acres of field to hunt them on with a nice size stock just across my back fence.

In time, I expect I'll have a nice collection of photos and get a better understanding of them along the way. In the meanwhile, I'll just observe and enjoy the photo opportunities that I can get. :)
