Daily Postcard: A Two-tailed Swallowtail butterfly sips nectar from the bloom of an Autumn Sage (Salvia Greggii) recently in the garden of a residence on Barranca Mesa. The Two-tailed Swallowtail is the official state butterfly of Arizona. (The Sandia Hairstreak is the state butterfly of New Mexico here.) Source: statesymbolsusa.org. Photo by Selvi Viswanathan
