Calopteryx virgo (Beautiful Demoiselle)

Something called a Beautiful Demoiselle sounds, to me, as though it’s been named by a 9-year old schoolgirl. Be that as it may, it is rather appropriate. We were captivated by them first at La Rigole near La Prise d’Eau d’Alzeau near Saissac, France.

In the UK, these have to be distinguished only from C. splendens (Banded Demoiselle) but in parts of France C. xanthostoma (Western Demoiselle) must also be considered. My Demoiselle Comparison Chart may help clarify the differences.
