Leptocircini Papilionini Troidini Teinopalpini Papilioninae is a subfamily of the butterfly family Papilionidae.

Papilioninae are swallowtail butterflies and are found worldwide, but most species are distributed in the tropics and warmer regions.

Papilioninae can survive in majority of habitat types, including tropics, alpine, and even subarctic.

[2] Larvae hatch and remain on a host plant, called a food-plant, until their adult stage.

[4] There is a very broad range of host plant preferences, which may be the reason this subfamily has been very evolutionarily successful.
