Papilio troilus
Typically, the wingspan of a Spicebush Swallowtail ranges from 3-4 inches.[8] Adults are primarily black/brown in color, with a trademark green-blue (male) or bright blue (female) splotch in the shape of a half moon on the hind-wings. The forewing has a border of cream-colored, oval spots. In the middle portion of the wing, the spots can be moon-shaped and a light blue in color.[6] Both sexes have cream-yellow moon-shaped spots on the edges of the hind-wings and a bright, orange spot at the base of the wings.[9] In females, the orange spot at the base of the wings will turn a greenish-white shade in summer, but not the spring.
Butterflies and Moths of North America experts finally verified my spotting as a Spicebush Swallowtail, they added my pictures to their website which I provided the link for. =)
I'm pretty sure this is a Tiger swallowtail though the color looks a little off. If it were a black swallowtail there would be a row of yellow patches above the blue - see photo 9 http://www.butterfliesandmoths.org/speci...
