Spicebush Swallowtail (Papilio troilus) 2006-05-21 Parvin State Park, NJ
How to tell a Spicebush Swallowtail from all the other dark Swallowtails:
Of all the dark Swallowtails, only the Spicebush underside has one spot that is not orange. The point may show a hint of orange from one individual to another, but won't be mistaken for an orange spot.
