What an exciting butterfly day I had! A Giant Swallowtail, Papillio Cresphontes in the front gardens; then another!
They were joined by several other butterflies, including a Tiger Swallowtail, shown here, and Gulf Frits, Spicebush Swallowtail and Sulphurs.
Their nectar of choice was definitely Tithonia, ignoring lantana, marigolds and some other delicacies like salvias.
I was thrilled to see this big fellow. Last year I thought a Giant Swallowtail showed up. It turned out to be a Palimedes, not nearly so big and lacking the yellow tips on the 'tails.' I thought it interesting that the Tiger and the Giants were playing together so well.
