Orthoporus ornatus
Orthoporus • Spirostreptidae

A hardy, handleable desert millipede and a classic beginner species — long-lived (around a decade with good care). Unlike tropical millipedes it needs strong ventilation: moisten only about a third of the substrate (deep, loose, with oak leaf litter on top) and let the rest stay drier, targeting 60-80% humidity without stagnation. Room warmth (75-80°F); never put a heat mat under the substrate. A detritivore — the leaf litter and rotting wood are its food, plus a calcium source. Harmless, though it can release a staining defensive fluid, so wash hands after handling.
