Often admired for its vibrant coloration and delicate form, this butterfly is more than just an aesthetic marvel; it is an emblem of ecological adaptability, evolutionary uniqueness, and expanding biogeographic boundaries. Although once restricted to South and Southeast Asia, its range has recently extended to new territories, making it a fascinating case study in insect migration and colonization.
