Some of the biggest and most beautiful bugs in the world live right here on the island of Papua, New Guinea. It's known as the land of the unexpected: a land of steep mountains, deep valleys and many different tribes' people who between them speak over 800 languages. Probably more than a quarter of a million insect species and around 900 different butterflies are here, and I'm on my way to find the world's biggest and some say the most beautiful butterfly: the Queen Alexandra Birdwing butterfly.
