About

The beautiful demoiselle may look like a dragonfly, but it is in fact a large damselfly. The males are metallic blue and the females green. They live on small, fast flowing rivers in the west of the UK. They can be seen flitting and fluttering over head as the male tries to attract a female with its impressive dance moves!

How to identify

Male Beautiful demoiselles have dark-coloured wings and metallic blue-green bodies; females have brown wings and green bodies. The Beautiful demoiselle is similar to the Banded Demoiselle, but the males of the latter species have distinctive dark patches in the middle of their wings.

In our area

Beautiful Demoiselle is widespread in Montgomeryshire, in all but the mountainous areas.

Distribution

Found west of a line drawn from Liverpool to Folkestone, where it is locally abundant.

Habitats
