The Zebra Swallowtail (Eurytides marcellus) is one of Georgia’s most beautiful butterflies, easily distinguished from other swallowtails by its long greenish-white and black pattern, said to be reminiscent of a zebra. It also has notably longer tails than other swallowtails in Georgia. They can be found in numerous environments, and are occasionally even spotted in yards, but most commonly gather in overgrazed pastures and roadsides. This individual was photographed in August 2009 on Dickson Mill Pond Road, not far from the Ocmulgee River. Someone who knows plants better than I do may be able to confirm, but I believe it’s feeding on a Green Milkweed (Asclepias viridis). Swallowtails are known to have an affinity for a variety of milkweeds.
