Love is in the air

Took my camera to Stover Park in Devon to film a white stork, my wife and I spotted the day before. Alas no stork arrived that day. And no it definately wasn't a heron!

But there was something else I spotted flying past my lense. A pair of dragonfly mating in mid air. Intrigued, I followed the bugs to a place where I could film them close up and got close enough to see fertilization taking place as fluids passed from the male to the female. [:I] I think this video would prove a great asset to biology classes.

Fascinating little vid, hope you enjoy it.

Don't forget to rate the little Bugs performance.

Andrew

Andrew, I find it really fascinating.
I didn’t know that exist specie by whom is possible to see with necked aye how fluids passing from the male to the female. I watch a few times but I couldn’t see that. I think it is because the picture isn’t sharp enough and this partly white background is responsible for poor contrast. I suggest next time use a tripod.

Aqcording to Wikipedia “Dragonflies do not normally bite or sting humans (though they will bite in order to escape, for example, if grasped by the abdomen); in fact, they are valued as a predator that helps control the populations of harmful insects, such as mosquitoes. It is because of this that dragonflies are sometimes called "mosquito hawks" in North America" http://en.wikipedia.org/wiki/Dragonfly

So because of blur picture I can’t rate “litle bugs performance” but because of the fact that more dragonflies means les mosquitos I wish them plenty ofspring.

The fluids can be seen as they emerge from the male in a droplet, which appears to be sucked in by the female, this happens several times and you can see the light reflecting in the fluid as it happens

The camera I had was limited with video capabilities, doubt I will ever observe this again either just happend to have a camera handy at the time.

I see what you mean.

By the way, here is web site of British Dragonfly Society. http://www.dragonflysoc.org.uk/

I guess, they will be interesting to see this video
