Western Minus-tail Butterfly

 Formerly known as the Western Swallowtail, it showed up when I was finished photographing the Red Milkweed Beetle on the small remaining patch of Asclepias speciosa on the western end of Chandler Road.  I was about to leave, and was having a chat with a fellow who stopped to see what I was doing.  This Swallowtail flew in and flitted from flower to flower, then circled the area a couple of times, and repeated the sequence several times.  The lack of a right "tail" piece didn't seem to impede its flight skills.
