Clouds of swallowtails and birdwings drifted through the humid air above a river that plunged over limestone ledges into deep green pools. The karst towers rose nearly vertical on both sides, their walls pocked with caves that held paintings older than any civilization. Wallace spent three months here, cataloging 256 butterfly species and filling crates with specimens that would help him develop the theory of evolution by natural selection -- independently of Darwin, and an ocean away from Victorian England.

Sulawesi sits in the biogeographic transition zone between Asia and Australia, a position that has blessed Bantimurung-Bulusaraung with an astonishing roster of endemic species. The dark-furred Sulawesi moor macaque moves through the canopy in troops, while the red-knobbed hornbi...

A 1977 survey by the researcher Mattimu found 103 species within the park boundaries, including endemics such as Papilio blumei, with its electric-green wing patches, and Graphium androcles, the largest...

The park lies just twenty kilometers from Sultan Hasanuddin International Airport, making the transition from modern Makass...
