Emerald Swallowtail

Papilio palinurus


Emerald Swallowtail has a wingspan reaching about 3.1–3.9 in. The dorsal sides of the wings are covered by a powder of green scales and the background vary from dark greenish to black, with broad bright emerald green metallic bands. The undersides are black with orange, white and blue spots along the edges of hind wings, that show extended tails at the end. The flight of these butterflies is swift and quite fast. Caterpillars feed on plants of the rue or citrus family. The iridescent green sheen of the bands of this butterfly is not produced by pigments, but is structural coloration produced by the microstructure of the wing scales. They refract the light and give rise to blue and yellow visible reflections, producing the perception of green colour when additively mixed.

I wasn't sure because although its captive in the US it is found within the range of your mission, so you understand why I thought it was ok . I put it in global butterfly mission only one I could find.

Thank you Keith. As much as we would love to have this spotting included, I regret that it is a Local Mission which could only include spottings anywhere inside the Philippines. That is a limitation we have to comply to. Global Missions, on the other hand, are the ones without this restriction. Regards.

It was intentional as this is one area its native to

Hello Keith. This is a beautiful swallowtail, although you may have unintentionally included this in the "Butterflies in the Philippines" mission. :)
