Porcellionides pruinosus — Oreo Crumble Isopods

Fast, active, and incredibly productive, Porcellionides pruinosus, commonly known as Powder Isopods, are an excellent choice for bioactive terrariums, vivariums, and starter isopod colonies.

Powder Isopods get their name from the distinctive dusty or “powdered” appearance of their exoskeleton. Unlike slower, more secretive species, these isopods are quick on their feet and can often be seen exploring the enclosure, especially around feeding time.

One of their biggest advantages is their rapid reproduction rate. Once established, a healthy colony can grow quickly, making Powder Isopods an excellent choice for keepers looking for a dependable and productive cleanup crew.

They feed on decaying leaves, wood, leftover food, and other organic material, helping recycle nutrients and keep bioactive substrates functioning naturally. Their adaptability also makes them suitable for a wide variety of bioactive setups.

Highlights

• Excellent bioactive cleanup crew

• Very active and fast moving

• Fast reproduction

• Hardy and beginner friendly

• Helps break down decaying organic matter

• Adapts to a variety of enclosure conditions

• Great choice for establishing large colonies

Powder Isopods do best with a moisture gradient, allowing them to move between damp and drier areas as needed. Provide plenty of leaf litter, decaying hardwood, hiding areas, and a calcium source. Supplemental isopod food and occasional protein can help support a rapidly growing colony.

Whether you're building a bioactive enclosure or starting a standalone culture, Porcellionides pruinosus are a hardy, productive, and entertaining species that earns its place in almost any isopod collection.
