The banded demoiselle is a damselfly and not a dragonfly. The damselfly has a very long, slender abdomen and, when not flying, usually holds its long stiff wings together with tips touching over its back. In contrast, the dragonfly generally has a plumper appearing abdomen and when resting, holds its wings straight out from its body in the same position as in flight.
The image was taken in the nature reserve La Petite Camargue Alsacienne a few days ago.
