Sorry- perhaps I haven't made myself clear-ants aren't the culprit-aphids are-the ants feed of the sugar secretions of the aphid-so if you see ants then there are aphids- you need to control the aphids.
Uncurl a leaf-what do you see?-if it isn't aphid it might be a caterpillar
I doubt that ants are responsible for the damage on your clematis either.
