What is eating the pokeweed?

I have learned to tolerate pokeweed (Phytolacca americana) in many places in my Missouri yard…where it provides lush greenery…eye-catching magenta stems…flowers for small pollinators…food for birds.

This is the first year I have noticed that something is eating the leaves.

I thought perhaps it could be Giant Leopard Moth (Hypercompe Scribonia) caterpillars that are reported to eat the plant….but I have never seen them on the plants.

I did see some frass one morning (the fly is for size comparison) but the caterpillars are apparently stealthy.  The mystery is not a bad thing necessarily; it motivates me to check the plants more frequently…and I’m pleased that the pokeweed leaves are food for something rather than remaining pristine!
