Black Swallowtails are part of the Swallowtail (Papilioniidae) family of butterflies. They are a mid-sized butterfly, with a wingspan between 6 and 9cm. There are typically 2-4 broods per year depending on local adaptations and temperatures. Caterpillars feed Fennel, Dill, Parsely, and their wild equivalents. These are easier to rear than their European cousin machaon, but following the care guides will help if you are unsure. Autumn pupae should be stored cold over winter until spring. Caring for the adult butterflies is straightforward
