Orthetrum chrysis In Wheel



This is the first time I have managed to get a photo of a pair of Orthetrum chrysis in wheel.

If this pair of dragonflies hadn't been in pursuit by another amorous male, I would not have spotted them from across the pond.

I had to practically run around the perimeter of the small pond as quickly and as quietly as I can to get to them.  I was lucky on this day.  This pair was still in wheel when I got close enough for a photo.

And not just one lucky shot this time, but two!




Based on what I have seen of this species, the Orthetrum chrysis has a very short courtship-copulation period and would usually be in wheel for only a brief moment before they separate.  Almost immediately after that, the pair will fly about to look for suitable egg laying sites before the female begin laying her eggs in the pond by flicking the tip of her abdomen in the water in succession at quick intervals while the male dragonfly hovers over her in close proximity to keep guard and will give chase to other male dragonflies that come too close.

After that, the male will perch nearby in the same vicinity while the female flies away to hide. 

There have been times when the pair gets assaulted by another male before ovipositing is completed and sometimes the female may even be caught by another male before the egg laying can occur.

The whole cycle then starts all over again!
