Just beautiful

On a walk yesterday near Upton Mill in Northamptonshire I came across a group of Beautiful Demoiselles (Calopteryx virgo) sunning themselves.  These are mature males.

The immature males have a lighter green/blue colouration and brown wings with no wing spots.

This is another young male with a male Banded Demoiselle (Calopteryx splendens) flying in the background.

The females are green and gold with white wing spots (pterostigmata).
