Eastern Tiger Swallowtail

Hi Edelynn,
Thank you for submitting your lovely photos of a Tiger Swallowtail.  North America has at least five identified species of Tiger Swallowtails, but two can definitely be eliminated, including the Western Tiger Swallowtail, which according to BugGuide, ranges in:  “Western North America east to the edge of the Rocky Mountains.”  Michigan is an area where the ranges of two species, the Canadian Tiger Swallowtail and the Eastern Tiger Swallowtail, overlap, and the two species are closely related enough to interbreed, creating hybrids.  Since there is no blue on the hind wings, we believe this is a male Eastern Tiger Swallowtail,
Papilio glaucus, and you can read more about it on BugGuide.
