Coordinator notes: This is a difficult individual, coupled with the tricky location you're in. I've seen many spring individuals in northern PA with mixed characteristics such as this one, and I don't think there is a definitive answer what to call these. On iNat, most are left as "Tiger Swallowtails and allies" at the subgenus level. With that said, it appears there is some minimal separation between the ventral FW submarginal yellow spots, as well as the dark band along the anal margin of the HW does not extend to the half-way point between the wing edge and the first vein. Finally, the submarginal HW crescents keep more of a crescent shape, as opposed to the more "boxier" appearance of P. canadensis. The dark line separating the ventral HW yellow from blue is fairly straight, which would actually favor P. canadensis. However, overall there are more P. glaucus leaning traits. -jmgesell
