This swallowtail was lazily flying around in the back yard in Middle Tennessee(Murfreesboro) today so I had time to run for the camera, I just wanted to share this awesome butterfly with you.
Is it a male or female?

Dear Rae,
Though Tennessee is a state where the range of the Eastern Tiger Swallowtail and the Appalachian Tiger Swallowtail overlap, we believe you have a photo of an Eastern Tiger Swallowtail, Papilio glaucus.  Your individual is a female as evidenced by the blue pattern on the lower wings.  According to BugGuide:  “Light phase females show blue on hindwing above.”  This photo of a female Eastern Tiger Swallowtail from BugGuide illustrates the blue markings.
