|The Eastern Tiger Swallowtail is one of the most familiar butterflies here in the American midwest. Common in forests and along streams, the tiger swallowtail is equally at home in urban gardens. |
Found in the Eastern United States as far north as Vermont and as far west as Colorado. Flies from spring through fall, and most of the year in the southern portions of its range, where it may produce two or three broods a year. In the Appalachian region, it is replaced by the closely-related and only recently described larger-sized Papilio appalachiensis, and in the north, it is replaced by the closely-related Papilio canadensis. These three species can be very difficult to distinguish, and were formerly all considered to be a single species 
Adult males are yellow, with four black "tiger stripes" on each fore wing. The trailing edges of the fore and hind wings are black which is broken with yellow spots. On the medial margin of the hind wing next to the abdomen there are small red and blue spots.
Eastern tiger swallowtail is the state butterfly of Georgia, Virginia, Alabama, South Carolina and Delaware.
