Experience the Wonder of Metamorphosis: Raise Your Own Black Swallowtail Butterflies

Embark on an immersive journey into the life of one of North America’s most striking insects. The Black Swallowtail caterpillar is a master of disguise and a marvel of biological development. By ordering our caterpillars, you will provide your family or students with a front-row seat to an incredible series of transformations.

The Journey of a Black Swallowtail

Your adventure begins when you receive a shipment of approximately 10 Black Swallowtail caterpillars, nestled on fresh, fragrant sprigs of dill or fennel.

• A Changing Masterpiece: These caterpillars are uniquely fascinating because they change appearance dramatically as they grow. As they molt through their different larval phases (instars), they evolve from dark, bird-dropping-mimicking forms into vibrant, lime-green caterpillars with stunning black and yellow bands. Watching these color shifts is a captivating lesson in nature’s ingenuity.
• The Hosting Phase: Your caterpillars will continue to thrive on the dill or fennel they arrive on. As they grow, they will also readily enjoy parsley and Queen Anne’s Lace. Providing these host plants is simple and deeply rewarding.
• The Great Wait: Once your caterpillars form their protective, silk-anchored chrysalises, the final, patient phase begins. Depending on the time of year, these hardy chrysalises may emerge in a few weeks, or they may enter a stage of dormancy, potentially remaining in their pupal state for up to 9 months before emerging as magnificent butterflies. This provides a unique, long-term opportunity to witness nature’s patience and timing.

Why Raise Black Swallowtails?

• Dynamic Visual Growth: The striking color changes during their larval stages offer an unparalleled opportunity to observe insect anatomy and development in real time.
• A Lesson in Patience: The potentially long wait for the adult butterfly to emerge teaches valuable lessons about resilience and timing, making the eventual emergence a truly celebrated event.
• Support Local Pollinators: By raising these iconic swallowtails, you are contributing to the health of your local ecosystem. Nurturing them from larvae to flight is a profound way to foster a lifelong love for conservation.
• A Captivating Experience: From the initial arrival of your caterpillars to the quiet mystery of the chrysalis, this experience provides endless curiosity for children and adults alike.

Getting Started

Your caterpillars arrive ready for their next meal. To keep them flourishing, simply ensure they have a steady supply of fresh dill, fennel, parsley, or Queen Anne’s Lace. We recommend having a small patch of these herbs in your garden or available from your local grocer to keep them well-fed until they are ready to pupate.
