Coordinator notes: I still have trouble differentiating Thoas & Giant, but my take on this is Thoas, though never 100% sure. ---- Well, I was wrong! And thanks to David Hoag for finding this error and I'm now changing it to Western Giant Swallowtail / Papilio rumiko. REASON GIVEN: "Pointed (not blunt) spots in the forewing median row. Only 3 submarginal spots on the FW."
