This resembles a Fall Webworm, a native species, though there are a number of other caterpillars (many in the tiger moth group) that have a similar body pattern and long hairs. Fall Webworm can have several color morphs for their caterpillars, which makes ID a little tricky. If this is a webworm, either it fell out of the host tree or it has finished feeding and is wandering about to find a place to pupate (form a cocoon), since many butterfly and moth caterpillars leave their host plant to wander since that makes them less easy to detect by predators.

Thank you!  I have seen the all white moth with orange head.

You're welcome.
