Great, thank you! I think you're right. I've just never seen this variety before, I've only seen little yellow ones on leaves. Apparently there are many types, though, some can get up to 1cm in size - yuck! Anyone who has the same thing, take a look here.... https://www.rhs.org.uk/advice/profile?PID=224
I've got too many to rub off, they are literally covering every branch. So if anyone has had success controlling them, advice would be appreciated! Otherwise, I'll just have to spray the tree, as advised on the linked rhs page.
