Some of the blue ones will be desperate females. They come in both colours.

Don't know a lot about mating damselflies, but the front one appears to be the male. He uses the end of his body to clasp the female around her neck.

Several more blue damselfies seen today, is the male green?-

Other way round. The green one is the female.-

Ah, thanks Kay. So we have a lot of desperate males around!

Thanks, Kay, we've certainly seen a few pairs looking for somewhere to
lay eggs, flitting around the ponds and causing a flurry of delighted
shrieks from children who spot them. They're such pretty little
flashes of irridescence.

Fascinating. And what fantastic photographs. Thank you, David.

A bit earlier in the year you can see them emerging - the larvae crawl out of the water, then slit their case and the adult emerges and clings to the vegetation for a few ours while they pump up their wings and get ready to fly - a vulnerable time for them. And if you look carefully on stems and leaves of emergent plants you may find lots of discarded exo-skeletons - looking just like the damselfly larvae in the pond, but empty!

One year I was lucky enough to find 3 cases of the much bigger dragon fly larvae on the pond just outside my study window.

I'm amazed any survive in the old pond here because it's teeming with
fish. But clearly they do. I'll look out for that. When's a good
time? May/June?

I don't know. Ours were emerging afterthe warm weather started, so that was some time in June. I suspect weather has something to do with it - maybe they don't emerge until the water has warmed up for example. And they come out on sunny mornings, not overcast or rainy days.
