which are all being eaten by something. ive no idea what it is? below

help???

First I'm absolutely sure that you don't have scale insects because
you'd have seen them (and so would I on your pictures), they're flat,
as big as my little finger's nail, brown, and are seriously stuck on
the bark of the branches. There's also lots of sticky white substance
associated with them. You haven't mentioned that. You have aphids and
plant lice, hence the curled leaves but also the ants. It's too late
to do anything once the leaves have curled up. I would keep hosing the
aphids out and let the ants do their stuff or introduce predators. Are
your plant in a greenhouse with other plants?. Also the big chunks out
of the leaves look like a catterpilar's doing. It has now flown
away ... )
