Only two species of damselfly in Britain have obviously coloured wings. They both belong to the genus Calopteryx. In this species the wings of the mature male are very dark blue-black and those of the female are iridescent brown-green. The body colour is metallic blue-green in the male and green with a bronze tip in the female. The flight is fluttering, butterfly-like.
Flight Period: May (April) – August (September)
Length: 17 mm
Long ‘horn-like’ antennae and long thin legs of the larva distinguish this as a demoiselle. The prominant ‘occipital tooth’ behind each eye and the single pale band on the caudal lamellae are distinctive to the Beautiful Demoiselle.
