Armadillidium maculatum, commonly known as the Zebra Isopod, is one of the most recognisable and popular Armadillidium species in the hobby. Native to the rocky, humid woodlands of southern France, this species is instantly identifiable by its bold black‑and‑white banding, a striking pattern that provides camouflage among dappled leaf litter and limestone rubble. Like all true pillbugs, they can roll into a tight defensive ball, a behaviour that protects them from predators and helps reduce moisture loss in their naturally variable environment.
 
In the wild, A. maculatum lives among decaying logs, mossy stones, and shaded forest floors, where pockets of moisture persist even in warm weather. They favour microhabitats that balance humidity with airflow—crevices beneath bark, gaps under stones, and the cool underside of rotting wood. Their diet consists of decaying leaves, softened wood, fungal growth, and the biofilm that coats natural debris. They are active, curious foragers, often seen exploring at the edges of their shelters when humidity rises.
 
In captivity, Zebra isopods thrive when these conditions are mirrored. They prefer a well‑ventilated enclosure with a moist retreat and a larger dry area, allowing them to regulate hydration without being exposed to constant dampness. A substrate mix of soil, sand, leaf litter, and rotting hardwood works beautifully, and they appreciate cork bark, bark slabs, and curved hides that mimic their natural refuges. Their bold patterning, active behaviour, and hardy nature make them a favourite for display setups and bioactive enclosures alike.
