Queen Alexandra’s Birdwing Butterfly - Largest Butterfly in the World #1633341 (License: Personal Use)

This stunning specimen of Ornithoptera alexandrae showcases its massive wingspan-up to 28 cm-and vivid coloration: iridescent turquoise-blue bands bordered by deep black veins, with a contrasting golden-yellow abdomen. Endemic to the rainforests of Papua New Guinea’s Oro Province, it is critically endangered due to habitat loss and illegal collection. Females are larger and less colorful than males, and the species relies on specific host plants like Aristolochia schlecteri for larval development.
