Under the cover of darkness, a butterfly with folded wings rests gracefully on a leaf in the Danum Valley Conservation Area in Sabah, Borneo. The 170-square-mile (438-square-kilometer) conservation area is the largest undisturbed lowland rain forest in Malaysia, home to one of the world's most complex ecosystems.
