Giant Swallowtail

For you butterfly aficionados, you probably already know that the backside pattern of the Giant Swallowtail and the Thoas Swallowtail at first glance look the same, but thanks to my favorite butterfly book I now know that there are slight differences in all those spots and the Thoas is a much lighter yellow or nearly white on black while the Giant is obviously a light yellow on black. Then the underside of the hind wings is the real giveaway with the Giant having a lot of blue spots and the Thoas only one little spec! So check it out the next time you see one of these! 🙂

Just two photos from my garden on Sunday of the Giant Swallowtail, Papilio cresphontes, with that link to website article, photos and map. And you might want to see my other photos of this giant in my gallery of Giant Swallowtails with some much better photos than these! 🙂
