Story 1: The Misidentified Monarch
In the early days of entomology, Queen Alexandra's birdwing was mistakenly named "Ornithoptera victoriae" in honor of Queen Victoria. It took several years for scientists to realize that the true monarch of the butterfly world was not named after the reigning monarch of England.
Story 2: The Overzealous Collector
One zealous collector determined to catch a Queen Alexandra's birdwing chased it for hours, only to end up crashing into a tree trunk. The butterfly escaped unharmed, while the collector was left with a bruised ego and a valuable lesson in patience.
Story 3: The Butterfly and the Tribe
A Papuan tribe once mistakenly believed that Queen Alexandra's birdwing contained spirits that could bestow blessings upon the tribe. However, it turned out that the "blessings" were actually caused by the butterfly's pheromones, which had a calming effect on the tribe members.
