Bug-ologist Needed — Empress Tree Being Eaten Alive?

I planted an Empress tree, a fast grower that has grown 4′ this summer. My problem is something is eating the leaves. The instructions said they don’t have bug problems, but mine does. I put Sevin dust on it, and still have the problem. I saw two tiny, bright red dots on a leaf. Do you know what bug that is and how to treat it? I live in Houston, Texas, a sub-tropical zone, so it could be anything.

Japanese Beetles? Grass hoppers? Could be caterpillars. what are the "munching" patterns.

J Beetles eat random holes — swiss cheese

G Hoppers are a little more selective — arcs removed

C Pillars ditto selective — neat tidy arcs
