Blue Mountain Swallowtail Post Earrings -- Papilio ulysses
Native to Indonesia, Australia, Papua New Guinea, and the Solomon Islands, this wonderful butterfly uses structural color within its wing scales to create a brilliant blue coloration. The wing scales reflect back the blue wavelengths of light, but do not contain their own pigment.
Two gorgeous real Blue Mountain Swallowtail wing sections, from one specimen for symmetry.
We use a small area on the forewings where wing veins meet.
