Answered the question I believe it is
While your caterpillar looks very similar to the link to our archives you cited, your Tiger Swallowtail caterpillar is most likely the originally described Eastern species, Papilio glaucus. While the appearances of the caterpillars of the three different Eastern species, we concede that you might have encountered an Appalacian Tiger Swallowtail caterpillar as you are within the BugGuide listed sightings, though there are no actual Virginia sightings. You are a little too far south to likely be the Canadian Tiger Swallowtail, which BugGuide reports only documented sightings considerably north of you, with the closest being Pennsylvania.
