What's the name of this butterfly? The unexpanded part of the wing is fluorescent blue. Very bright and beautiful.

Papilio Papilio, the front wing is 52~60 mm long, the wing bottom is black, and there are blue-green bright scales. The blue bright scales are mostly concentrated in the front edge of the rear wing, and the rear wing has a tail process.

The wings are triangular, the outer edge of the back wing is wavy and the body wing is black. The first half of the front wing is light in color, and golden yellow or golden blue or golden green scales are scattered between the veins. There are six pink or blue bird-shaped spots on the sub-outer edge of the hind wing and a semi-circular pink spot on the hip corner. The middle wing forms a large blue area, especially near the leading edge, and the reverse side is light in color with obvious markings. The medial cavity of the anterior and posterior wings is closed, with 5 R veins in the anterior wing, 2 A veins in the posterior wing and 1 pulse in the posterior wing. There are hooked veins in the shoulder, and M3 extends into a caudate process. The caudate process is also covered with blue and green bright scales, but only black scales form a black frame at the edge. The color and stripes of male and female butterflies are almost the same. There are 4~5 spindle-shaped fragrant scales in the sub-outer edge area, the outer middle area and the lower part of the middle area of the male butterfly, and the orange-red crescent pattern on the outer edge of the rear wing of the female butterfly is slightly more developed than that of the male butterfly.

I hope I can help you, and I hope to adopt it!
