Beautiful Demoiselle (Calopteryx virgo)

The Beautiful Demoiselle and the Banded Agrion rate as two of my favourite insects. Stunningly beautiful in the sun with their metallic finish making them look almost unreal, the colours just being possible to make!
The Banded Agrion is quite common but the Beautiful Demoiselle less so, it having particular preferences in habitat. The Beautiful Demoiselle likes fast flowing clear, unpolluted water with abundant aquatic vegetation. The upper reaches of some of Dorset's chalk streams are ideal for them.
This preference for a special habitat means they are far from common anywhere. They are also inclined not to move far from where they laid their eggs so are, by nature, a local species.
It is the absence of the dark patches on the wings that immediately distinguishes them from the Banded Agrion.
