Beautiful Demoiselle

The Beautiful Demoiselle (Calopteryx virgo) was extinct in Norfolk, with the last record being in the 1970's, until 2006 brought reports from four seperate locations in Norfolk. Since the nearest known colony is in Essex, it seems likely that these were continental migrants - particularly as they were seen during a period of exceptional migration. Although no breeding was observed, the possibility of a new colony being formed must be considered, and it should be kept in mind when observing the closly related and common Banded Demoiselle (Calopteryx splendens)

Identification

Great care should be taken to distinquish this from the very similar Banded Demoiselle. The male has a metallic light blue body and bright purple-brown wing markings which cover the whole of the wings. (The banded has a darker blue body with the markings covering only the middle half of the wing. Females have dark green metallic bodies and smoky brown wings - Beautiful's have green wing colouring and a lighter green body, but great care is needed to distinquish between them.
