Giant Sulawesi Cherry Back Millipede — Undescribed sp.
The Giant Sulawesi Cherry Back Millipede combines a substantial, thick-bodied build with color that photographs struggle to capture. At approximately 5 to 5.5 inches, this heavy-bodied Indonesian millipede displays a deep, glossy cherry-red back, iridescent purple sides, and golden-yellow legs and antennae. Its broad body gives those contrasting colors plenty of surface area, making the Cherry Back a striking addition to a tropical millipede collection.
Lighting reveals its most distinctive feature. As the viewing angle changes, the purple sides catch an iridescent sheen that a still photograph rarely conveys completely. In good light, that shifting color is immediately noticeable in person, especially against the rich red of the upper body.

Sulawesi: An Island Shaped by Isolation
Sulawesi lies within Wallacea, the island region between the continental shelves of Asia and Australia. Deep-water barriers limited movement from those neighboring landmasses, even when lower sea levels connected many other Indonesian islands. That long isolation helped produce Sulawesi’s unusually distinctive wildlife.
The island itself developed through the assembly of smaller landmasses. Its mountainous arms, deep bays, and ancient lakes reflect a complicated geological history that created opportunities for animal populations to become separated and develop independently. This regional background makes Sulawesi especially interesting to invertebrate keepers, although the Cherry Back’s precise collection locality and natural range are not established here.
Collectors interested in the island’s contrasting millipede colors can also explore the Giant Sunfire Millipede. The Cherry Back brings its own recognizable combination to that selection: a broad red back, dark purple sides, and bright yellow appendages.
Building the Enclosure Around the Millipede
For a millipede of this size, the enclosure’s usable floor space and substrate deserve particular attention. Provide room to move and burrow, with a substantial layer of suitable millipede substrate containing decomposed hardwood and decaying leaves. These materials serve as both habitat and food; decorative bark alone does not replace them.
Maintain moisture within the substrate while allowing ventilation and avoiding waterlogged conditions. Leaf litter and pieces of decayed hardwood add feeding surfaces and sheltered areas. Supplemental foods should complement the decomposing plant material available throughout the enclosure.
Our Vivarium Naturals collection of vivarium supplies includes substrates and materials for a range of enclosure projects, from Bio-Thrive Millipede Substrate and Arachno-Thrive Tarantula Burrowing Substrate to vivarium-grade sphagnum moss, expanded clay nodules for drainage, and more. Choose the substrate formulation appropriate to the animal; Bio-Thrive Millipede Substrate is the millipede-focused option in the range.
For another distinctive Sulawesi display animal, consider the Giant Porcelain Tiger Millipede. Together, these different forms show why the island has become such an interesting source of millipedes for collectors.
The Giant Sulawesi Cherry Back Millipede stands out through the combination of substantial size, exceptional body thickness, and a glossy red-and-purple finish best appreciated in person.
