Thanks Arp.
As far as I know these are the same larvae that started this thread.
They are on a container plant that was on its own although I have started to move other plants in its direction to boost the supply of aphids!
Here are a couple more shots, although I'm not sure if they are old enough to distinguish anything as they still look quite light.
I'll put them on just in case but I'll look out for some more tomorrow.
Thanks
