A common understanding as to the decision on is it a Dragonfly or a Damselfly is decided by the rest position of the wings, 90 degrees to the body = Dragonfly, along the line of the body = Damselfly, so, as always there is an exception to the rule. The (Chalco) lestes species of Damsels, in this case the Chalcolestes viridis, the Willow Emerald Damselfly rests its wings at 45 degrees to the body, Taken today at lac Montbel, Aude, S. France.
