Just watching an interesting David Attenborough programme 'Deagons & Damsels' on Sky Mix on freeview CH 11
Edit: A fabulous programme, so well filmed and offering a great insight into these creatures lives plus talking about Willow Emeralds being an invader since 2007 and a marker of climate change ... well worth watching if you can get it on playback!
