When caterpillars are ready to pupate, they leave their foodplant and wander around, sometimes quite a distance, looking for a safe place to build a cocoon. Some of them pupate underground and want to dig in the dirt. This specimen has left an oak tree and is looking for a place to hold up for a while.
