Imperial Moth Caterpillar

Dear Cindy,
This is indeed an Imperial Moth Caterpillar, and its darker coloration indicates it is getting ready to pupate.  Caterpillars will frequently change color and leave the host plant when it is time to pupate, so we are guessing it was found on the ground as Imperial Moth Caterpillars pupate underground.
