Caterpillar found in Norther California

My son brought home this caterpillar from a close by river. We still have it in his bug catcher with some leaves and other foliage from there and it has since cocooned.
I am curious as to what this is.
Sacramento, CA at the American River
This is the caterpillar of a Pipevine Swallowtail, Battus philenor, a lovely blue-green butterfly with orange spots on the undersides of the wings.
