What is a Swallowtail Butterfly?

Swallowtail butterflies belong to the Papilionidae superfamily (Papilionidae Latreille family). They’re large, brightly colored, with tails on their hind wings (with the exceptions of Indra and Polydamus). These tails are their main characteristic. This family has over 600 species globally, and many people love them.

Some species of Swallowtails are black and share similar yellow, blue, and orange patterns. This makes the identification difficult, and people often mix some of the most common Swallowtail butterflies.
