This one-off investigative documentary looks into all stages of the exotic buttefly trade, from the underground groups paying thousands in Japan to the conservationists of Indonesia fighting to keep endangered species from extinction.

Every year, more than 100,000 butterflies are shipped across the globe to be sold as collectibles. Among them, some of the most unique butterfly species that come from Indonesia. The country’s biodiverse habitat is home to more than 2,000 species. And it has fuelled a growing global industry of butterfly hunters and dealers, with some operating in the black market.

Undercover Asia follows the trails of these alluring insects, from Japan to Indonesia to investigate first-hand how they secretly change hands among hunters, dealers and collectors.
