Spicebush Swallowtail ~ Papilio Troilus Ilioneus

This spicebush swallowtail butterfly was as fresh as fresh could be. And very hard to catch sitting still. Googling reveals that there are two types of spicebush swallowtails - Papilio troilus ilioneus and Papilio troilus troilus - and theoretically the latter is more likely in Virginia. But looking at the photos, I'd say this one is the former. In any case - it's a spicebush swallowtail.
