Beautiful Demoiselle (Calopteryx virgo )

BACK TO Back To Homepage ...Back To Insects

Family Calopterygidae

Flight Period Adults fly during June and July.



Males have a metallic blue-green body and broad, dark wings with iridescent veins
Females have a brilliant metallic green body and the wings are tinted golden brown with a distinctive white pseudo-pterostigma

This species is very similar to the Banded Demoiselle Calopteryx splendens. The males of the two species can easily be distinguished as in C. splendens the wing pigment is confined to a broad central band whereas in C. virgo it covers the entire wing. The females are more difficult to separate but in C. virgo the wings are broader and have a brownish tint whilst in C. splendens the wings are tinted green.
