Eastern Tiger Swallowtails are huge, bright butterflies that are commonly seen east of the Mississippi River. They are a variety of forms, varying in color by age and sex. The most popular form has black, tiger-like striping on yellow wings. Males are mostly yellow with black edges, but females have waves of blue and orange at the edges of their wings. Young females hardly resemble their more mature selves. They are mostly black with blue along the bottom edges of the wings. This darker coloring is more common in the southern U.S. whereas the classic yellow coloring is more typical in northern states. All Eastern Tiger Swallowtails have a long tail-like extension at the bottom of each hindwing.
This species has the honor of being the state butterfly of five eastern states: Delaware, Georgia, North Carolina, South Carolina and Virginia. As a member of the Swallowtail family, it joins its relatives in being the largest group of butterflies on the continent. They are extremely easy to attract, flocking to gardens that have an abundance of flowers. They are good pollinators and worth attracting for aesthetic reasons as well. They can also be seen flying on open roads, in woods, meadows, fields and parks.

* MAP NOTES: The territorial heat map above showcases (in red) the states and territories of North America where the Eastern Tiger Swallowtail may be found (but is not limited to). This sort of data is useful when attempting to see concentrations of particular species across the continent as well as revealing possible migratory patterns over a species' given lifespan. Some insects are naturally confined by environment, weather, mating habits, food resources and the like while others see widespread expansion across most, or all, of North America. States/Territories shown above are a general indicator of areas inhabited by the Eastern Tiger Swallowtail. Insects generally go where they please, typically driven by diet, environmental changes, and / or mating habits.
