Thursday was a good day for demoiselles. As I strolled along the old Glamorgan canal at Forest Farm Nature Reserve, I was almost constantly entertained by both the Beautiful (Calopteryx virgo) and the Banded demoiselles (Calopteryx splendens), though there were definitely many more of the former than the latter.

While the females mostly perched quietly on leaves somewhat removed from the males – the only way to escape their attention, the males seldom kept still. They flashed their wings, displaying their metallic blue hues to impress any female that did venture past, and competed with other males for the best territories, those with sun, and shelter, and perches, and suitable places for egg-laying. What was serious breeding business for these stunning creatures was enchanting and magical for me.

Banded Demoiselle, Calopteryx splendens, damselflies, damselfy, National Dragonfly Week 2016

On the first day of National Dragonfly Week I showed you the Beautiful Demoiselle; today we have the other damselfly in the Demoiselle species, the only damselflies in Britain to have coloured wings. This is the Banded Demoiselle (Calopteryx splendens), and you can see immediately from the bands of colour on the males’ wings how it got its common name.

These damselflies are simply gorgeous, the male (above) a stunning metallic blue and the female (below) an equally spectacular metallic green. Common in Wales and all but the northernmost counties of England, they can be seen flying around lakes and ponds and along canals and slow-moving rivers and streams, from late April to early September. Banded Demoiselles are quite sensitive to pollution so their presence is a good sign that the local water source is clean.

I wonder if this female knew about the spider, or the spider knew about the damselfly?

The male is territorial and also a bit of a show-off. He performs a delightful display of aeronautic dance moves in his attempts to impress the females – the damselfly version of Patrick Swayze in Dirty Dancing!
