Whatever kind of critter is doing this doesn't 'eat' the leaves, it just rips them. It seems to go around the leaf perimeter, tearing the leaves, pulling back rips from the outside of the leaf inwards, and it leaves the torn parts attached to the leaf. It likes leaves far from the ground, near the highest point of the plants. Most of the worst of the damage is on plants that have grown up to the underside of the soffit.
I have never seen anything doing this damage and I have been looking for many days now. Could it be wasps, or ants?
Thanks for your consideration,
