Species information


Length: 4.5cm

When to see

May to August


The Beautiful demoiselle is a large damselfly that lives on small, fast-flowing rivers, mainly in the west of the country. It is one of only two UK damselflies with obviously coloured wings; the similar-looking Banded demoiselle, however, has distinctive dark patches on its wings. The Beautiful demoiselle is typically on the wing from May to August. It displays a flitting, fluttering flight, which the male uses to attract a female.

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.


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

Did you know?

Male Beautiful demoiselles rest on bankside vegetation awaiting passing females. They use their fluttering flight as a courtship display.
