First exploration of Bantimurung area was done by Alfred Wallace in July–October 1857. Later, he published his exploration result in a book "The Malay Archipelago" which attracted lots of researcher came to Maros.
Located in the transition area of Asia and Australia zone, the National Park has many unique animals collection, such as Sulawesi Moor Macaque (Macaca maura), the Red-knobbed Hornbill (Aceros cassidix, Penelopides exarhatus), cuscus (Strigocuscus celebensis), Sulawesi palm civet (Macrogalidia musschenbroekii), bat, and pot-bellied boar (Sus scrofa vittatus). Recently, in March 2008, staffs of Bantimurung - Bulusaraung National Park had documented the existence of Tarsius fuscus (the smallest mammalian) and they also found its nest inside the area. Among crustacean biodiversity in the karst area, there is one unique species called "spider crab" (Cancrocaeca xenomorpha) which is only found in Maros Karst cave.
Besides insectarium, butterfly breeding centers, managed by both the reserve administrator and residents serve complete the metamorphosis process of the butterflies. There are many butterflies around the waterfall such as Troides helena Linne, 'Troides hypolitus' Cramer, Troides haliphron Boisduval, Papilio peranthus adamantius and Cethosia myrana. Alfred Russel Wallace dubbed the place as the Butterfly Kingdom. During his exploration in 1957, Wallace found 256 butterfly species from Bantimurung area, different from previous report of Mattimu in 1977 who found 103 butterfly species inside the National Park with some endemic species are Papilio blumei, Papilio polytes, Papilio sataspes, and Graphium androcles.
Since 1970s, butterflies already became export commodity from Bantimurung area. Not only sell to foreign countries, the local market also use this animals as materials for souvenirs, such as raw specimen, butterfly frame, key chain, and many other accessories. In 2010, about 600.000 tourists came to this conservatory site and the management of this National Park changed the purpose of this butterfly conservatory from extraction and exploitation into natural ecosystem for tourist attraction. However, some sellers still catch and use butterflies from its original habitat, not from breeding or farming production. To preserve this animal, Indonesia government through National Species Conservation Strategic Directions 2008-2018, included wide variety of butterfly as one of priority in insect group.
