The Pipevine Swallowtail is a striking butterfly known for its iridescent blue-black wings. It belongs to the family Papilionidae and is commonly found in the eastern and southern regions of the United States. The larvae primarily feed on plants from the Aristolochia genus, also known as pipevines, which provide them with toxins that make them unpalatable to predators. Adult Pipevine Swallowtails are often seen in gardens and open fields, where they are attracted to nectar from various flowers. Their distinctive appearance and unique life cycle make them a fascinating subject for butterfly enthusiasts and researchers alike.
