Can anyone please help me identify this please.
I saw it on a nettle plant, I believe, and it was about 5 mm long. I assumed that it had some sort of detritus on top of it but when I tried to move it with a bit of grass, it was clear the black lump was attached.
I have attached two pictures to this email - if you need a higher resolution just let me know
Any help VERY gratefully received
I don't recognize it.
But I'm glad you photographed it and shared it here.
I think it is a great piece of camouflage and protection: carrying a piece of real or fabricated caterpillar frass (dung) on its back to guide foraging birds to look elsewhere for food. And the green part of the creature also mimics the leaf surface so well!
I look forward to somebody telling us what it is!
jag' - many thanks for the pointer - quite right.
The one you point to is a thistle feeder.
But Cassida viridis includes nettles in its menu, and looks extremely similar as a larva...
