The Zebra Swallowtail butterfly obviously suffers from attention deficit disorder. While the lackadaisical Monarch butterfly will perch on a flower for several minutes, the Zebra only dwells 2 or 3 seconds on a flower and then is off to greener pastures. I had to chase this fellow from bush to bush to get this photo with my 300mm lens.
The only time the Zebra seems to be less excited is when it flies to a leaf on a tall tree where it looks as if it's catching its breath.
By the way, the Zebra Swallowtail is the official butterfly of the state of Tennessee. Why didn't the big orange Monarch get that distinction?
