Powder Blue (Porcellionides pruinosus)

Powder Blue isopods are the tiny workhorses of the bioactive world. With their soft blue-gray, slightly “dusty” appearance, they look like they’ve been lightly powdered in chalk—hence the name! Calm, efficient, and constantly on the move, these isopods are famous for getting the job done while staying mostly out of sight.

🌍 Origin

Porcellionides pruinosus originates from the Mediterranean region but has spread worldwide due to its incredible adaptability. Powder Blues are a popular captive-bred morph valued for their resilience, fast reproduction, and effectiveness in bioactive setups.

🪴 Basic Care

Powder Blue isopods are very beginner-friendly and thrive in a wide range of conditions.

• Humidity: Low to moderate with a clear moisture gradient

• Substrate: Well-draining bioactive mix with leaf litter, rotting wood, and calcium sources

• Temperature: 68–85°F

• Diet: Leaf litter, decaying wood, vegetables, fish food, protein sources, and calcium (cuttlebone or eggshells)

• Ventilation: Good airflow is important; they tolerate drier conditions better than many species

They reproduce rapidly and establish large colonies quickly, making them an excellent choice for functional enclosures.

🧹 What They’re Known For

• Outstanding clean-up crew for arid and semi-arid bioactive enclosures

• Efficient at consuming waste, mold, and leftover food

• Commonly used with reptiles like geckos, bearded dragons, and snakes

• Fast breeders—great for sustaining active enclosures

• Hardy and forgiving, even with minor care mistakes

⭐ Why Choose Powder Blues?

• Subtle, attractive blue-gray coloration

• Extremely adaptable and resilient

• Perfect for beginners and experienced keepers alike

• Ideal for high-traffic bioactive habitats

Whether you’re creating a functional clean-up crew or expanding your isopod collection, Powder Blue isopods are a reliable, low-maintenance favorite that deliver consistent results.
