Although my walk around White Rock Lake yesterday did not last as long as I had hoped, its end did offer an encounter with a beautiful eastern tiger swallowtail butterfly (Papilio glaucus) as it fetched a drink from a puddle beneath a cottonwood tree.  It lingered in the middle of the mud pit which kept me at bay, yet I still was able to grab some images of this enormous piece of artwork from the edges of the wet patch.

[note that none of these photos are macro shots; I never got that close to the butterfly due to the mud and the ants that infested the periphery of the slick]
