The Black Swallowtail is a striking butterfly found in North America, known for its vibrant colors and distinctive markings. Its wings are primarily black with bright yellow spots and blue iridescence near the hindwings. The adult butterflies typically have a wingspan of 3 to 4 inches and are often seen in gardens, meadows, and open fields. The larvae, or caterpillars, of the Black Swallowtail feed on plants in the Apiaceae family, such as carrots and parsley. They undergo several molts before pupating into a chrysalis, where they transform into adult butterflies. This species plays a vital role in pollination, contributing to the health of various ecosystems.
