This large, beautiful butterfly is a dark morph of the yellow and black Eastern Tiger Swallowtail apparently. It apparently is attempting to imitate the appearance of the black with blue trim Pipevine Swallowtail which has the protection of being poisonous to birds. Here in SE Minnesota is the edge of the range of the Black ETSB and outside the range of the Pipevine (according to BAMONA) rendering the Black ETSB survival strategy rather doubtful locally. I never would have learned any of this interesting stuff if not for photography getting me involved with butterflies!
Nice image. Note the "Black" version is only females. All of the males are yellow & black. The females can be either yellow & black or all black. The way to tell a female is the presence of blue on the upper side of the hindwings. Lots of blue = female.

Thanks, Scott, for your nice and detailed comment. It's interesting that the F. has the dual morph apparently living as one set of colors or the other.
