Thank you for the help
I sure do appreciate you two identifying the butterflies, they are so interesting to me.

Giant Swallowtail
In Central Texas there are two swallowtails that look similar - the Giant Swallowtail (Papilio cresphontes) and the Western Giant Swallowtail (Papilio rumiko). The paper describing the Western Giant Swallowtail (described in December 2014) can be found at http://zookeys.pensoft.net/articles.php?id=4409.

Your photos appear to show a Giant Swallowtail (Papilio Cresphontes).

I think the near contiguous yellow bands on the tegulae point to this being Papilio rumiko. In P. cresphontes, there are distinct dots rather than bands. In central Texas, these two species can also hybridize.
