I took this shot last week and after some verification, posted the image here. I have been using the latest European Dragonfly Field Guide and initially id'd this as Blue Featherleg. I was told it was a White-legged Damselfly but it seems that the fieldguide likes to use both names! Anyway, it is a Platycnemis pennipes!
The image was taken near Perissac, Bordeaux using a 105mm macro lens.
