This colorful caterpillar stood out from the plain greenery which he was eating, which is how I happened to see him. A mob of Red-winged Black Birds was in the area and I was expecting him to get picked off as I watched.

He was methodically consuming the leaf, munching back and forth straight across the top.

A wider view shows there was some red foliage nearby, which may have helped camouflage him.
