Spotted White Tree Millipede Black Leg, Anadenobolus arboreus gundlachi | Captive Bred
The Spotted White Tree Millipede Black Leg (Anadenobolus arboreus gundlachi) is one of the most visually unusual millipedes available in the hobby. Its creamy white body is decorated with bright orange dorsal spots, while jet-black legs and black antennae create a dramatic contrast rarely seen in giant millipedes. The result is an appearance so crisp and colorful that many first-time observers assume it isn't real.
These captive-bred specimens represent a naturally occurring locality variation found within the mountain forests of Puerto Rico. The Defiant Forest also produces the Yellow Leg, Yellow Antennae locality, another naturally occurring regional form of the same subspecies. These color differences are not selectively bred—they occur naturally among isolated populations separated by Puerto Rico's rugged interior mountain ranges.

Native Habitat
Unlike many millipedes that spend nearly all of their lives beneath leaf litter, Anadenobolus arboreus gundlachi is frequently encountered climbing tree trunks, fallen branches, and moss-covered hardwoods throughout Puerto Rico's humid mountain forests.
Puerto Rico's Cordillera Central divides the island into numerous valleys, ridges, and isolated watersheds. Moist trade winds from the Atlantic and Caribbean rise over these mountains, producing cloud forests, dense tropical vegetation, and exceptionally humid conditions. Over thousands of years, these geographic barriers have allowed many plants and animals—including millipedes—to develop localized color forms that may differ from one mountain range to the next.
This Black Leg, Black Antennae variation is one example of that remarkable natural diversity.
Appearance
This locality immediately stands apart from nearly every other tree millipede in the hobby. The body is an ivory to creamy white, highlighted by vivid orange spots running along the back. Glossy black legs and equally black antennae create a bold contrast that makes the colors appear even brighter.
Its relatively slender body and strong climbing ability reflect its arboreal lifestyle. Rather than remaining buried for long periods, these millipedes are often observed exploring cork bark, hardwood branches, and elevated surfaces throughout the enclosure.
A Collector's Favorite
Because of its unusual coloration, island origin, and arboreal habits, Anadenobolus arboreus gundlachi has become one of the most sought-after Caribbean millipedes available. The striking appearance, combined with captive breeding, makes this an excellent addition for collectors looking to own something genuinely different from the larger African species commonly found in the hobby.
Each locality variation tells a story about the island's geography and how isolated mountain habitats can shape the appearance of a species over time.
Recommended Vivarium Supplies
A naturalistic enclosure allows this arboreal species to display more of its normal climbing behavior. Many keepers build their habitats using Vivarium Naturals products, including Terra Thrive Bioactive Vivarium Substrate, Vivarium Grade Sphagnum Moss, natural hardwoods, cork bark, and expanded clay drainage nodules when constructing larger planted vivariums. These materials help create a stable, humid environment while producing an attractive tropical display.
Whether you're expanding an advanced collection or searching for a truly distinctive captive-bred species, the Spotted White Tree Millipede Black Leg var. offers an uncommon combination of natural beauty, fascinating island origins, and exceptional display value.
