There are quite a number of Banded Demoiselle (Calopteryx splendens) flying now.
After period of wet weather I have observed them along the river bank on one of my walks.
This female below was moving along the bank and pitching on tall grass seed.
Only one chance to get this male before he moved off again.
A pair of Azure Blue (Coenagrion puella).
A male Azure Blue below.
Another female Banded Demoiselle
The Large Red Damselfly (Pyrrhosoma nymphula)
