Cairns Birdwing Ornithoptera euphorion

This is Australia's largest endemic butterfly—a genuine giant with wings that can span over 10 centimeters across. Native only to Queensland and found nowhere else in the world, this showstopper is called the Cairns birdwing, Cooktown birdwing, or northern birdwing depending on who you ask.

The names reference the Australian cities where it's found, places that have become synonymous with this spectacular insect. With iridescent green and black wings that make it one of the most sought-after sights for butterfly enthusiasts, this birdwing represents the absolute peak of Australia's endemic butterfly fauna.
