I have just popped out to the garden pond to see if there was any nightlife there, maybe a frog or a newt. No, not tonight. But to my utter surprise there was 30 to 40 or more of these Large Red Damselfly (Pyrrhosoma nymphula) larvae on rocks beneath the water apparently feeding on algae. I have seen one or two during the day, but now realise these are very much nocturnal feeders, and didn’t realise how many there were in there. The image of the nymph above was taken last year, so they have grown since then.
I think it all goes back to last year when I spotted this female Large Red Damselfly laying eggs at the bottom of my Water Mint. Apparently they can lay up to 350 eggs at a time!
