With its dramatic colours, regal name, and fascinating behaviours, it holds a special place in Southeast Asia's ecosystem and culture.
Whether you're a nature enthusiast or just curious about unique wildlife, here are five things you probably didn't know about this iconic insect:
1. The Rajah Brooke's birdwing was once used as diplomatic currency
During British colonial times, the Rajah Brooke's birdwing was sometimes presented to dignitaries — either as preserved specimens or through intricate illustrations. These rare offerings were part of the West's colonial-era fascination with Southeast Asia's lush biodiversity.

2. The regality doesn't stop there, as even the butterfly's name is fit for a king
It's named after James Brooke, the first 'White Rajah' of Sarawak, a British adventurer who became the ruler of a kingdom in Borneo. Naturalist Alfred Russel Wallace, who co-discovered the theory of natural selection, was so moved upon seeing the butterfly for the first time that he described experiencing intense emotion.

3. Surprisingly, the butterflies' taste buds before it transforms are more dangerous than those of most animals
In its larval stage, the Rajah Brooke's birdwing feeds exclusively on the toxic Dutchman's pipe vine (Aristolochia spp.), which is poisonous to most other animals. This toxic diet gives the butterfly a chemical defense — making the adult butterfly distasteful to predators.

4. It takes the "bird" aspect of its name quite literally
With a wingspan of up to 17cm, the butterfly glides through the air slowly and smoothly — more like a bird than a typical fluttering butterfly. This graceful motion, combined with its neon-green iridescent markings, helps deter predators and awe onlookers.

5. With its elegance and beauty, it became symbolic of Malaysia's national status
Due to its sheer uniqueness, it's no wonder why the Rajah Brooke's birdwing is constantly featured on Malaysian stamps, artwork, and household objects.
Not only is this very insect a reminder of the rich biodiversity Malaysia has to offer, but also how crucial it is to preserve it.
