The Thoas was selected due to range.

And the thoas is the king swallowtail, and the cresphontes is the giant, but there are pages calling them the same butterfly.

Matt, that's an amazing photo in your file. But now I'm totally confused. The common name says giant swallowtail and the scientific says Thoas nealces.

Picture of Thoas in my file. Quite a bit more black...

Either giant swallowtail (Papilio cresphontes) or thoas swallowtail (Papilio thoas). "It's been written that Papilio cresphontes & the following (Papilio thoas) are not distinguishable other than by the 'fingernail test'. In thoas, the back of the abdomen is smooth. In cresphontes, "'here is a distinct notch near the tip (of the abdomen).'"

Further notes on differences between the two:
