Not Spicebush: The inner or postmedian (some call this median) spot row is complete. The 3rd position in from the inner margin contains a spot. In Spicebush, the inner row is missing one orange spot (third in from the inner margin.)

I'm guessing...
Black swallowtail. Main reason: That orange spot at the bottom near the back of the hind wing with the black area inside. Black swallowtails have it. Spicebush swallowtails don't (at least, not in any picture I've ever seen).
Secondary reason: The colored area just in front of that spot on the inside of the L hind wing is a nice clear blue. In spicebush swallowtails, it tends to be green or greenish (though I have seen pictures where it looks blue).

Thanks
I'm leaning toward Black, too, but not sure. Always best to get a dorsal view too, but they don't always cooperate.
