Dragonfly sitting on a fence post.
I would not trust anything if I were you :D I think you should do some own research based on the ID suggestion, and see if you are able to find more examples with black wing-tips. The only thing we both know for sure is that it is a beautiful dragonfly on your picture :)
The photo in the link in the comment seems very promising, however the one in the ARKive is a little different on the wing tips. However, this is a lot further than I've come thus far. Can the Flikr link be trusted with the species identification?
There were not that much info in wiki or EOL, but I have a link for you with what I think is your spotting, with the blacked tipped wings here: http://www.flickr.com/photos/xx_chaton_x... There is also a bit of information about it in the red list of threatened species http://www.iucnredlist.org/details/16478...
I hope this helps, Tina
