Real-world information
The Queen Alexandra's birdwing (Ornithoptera alexandrae) is considered the largest butterfly in the world, named after Queen Alexandra, wife of King Edward VII of the United Kingdom. It was discovered by Albert Stewart Meek, who was employed by Lord Walter Rothschild (who named it) in 1907, in Papua New Guinea. It was shot down using a shotgun, but its early stages were discovered and bred through to get to this stage. The female birdwing has a wingspan of up to 31cm, while the male (which appears in game) has a smaller wingspan of up to 26cm. The birdwing flies quite high in the rainforest, making it hard to catch, which is the main reason hunters shoot them with shotguns. The birdwing in Animal Crossing also flies higher than usual butterflies, a reference to its flying habits in the real world.

The birdwing is endangered, threatened by habitat loss. Most of Papua New Guinea's rainforests were destroyed during a volcanic eruption, wiping out parts of the birdwing's habitat.
