Porcellio scaber – Lava Isopods

Porcellio scaber, lava morph is known for its intense, contrasting colours, is one of the most popular species of terrestrial isopods for bioactive terrariums and vivariums. These small detritivores crustaceans play a vital role as a natural "clean up crew," helping to keep bioactive terrariums clean, healthy and in ecological balance.

Characteristics of the Porcellio scaber Lava

The Lava morph of Porcellio scaber is distinguished by its irregular pattern with red, orange, yellow and black spots, reminiscent of glowing volcanic rock or lava flows. The body is robust, slightly grainy, with an average length of 1–1.5 cm. These are hardy, adaptable isopods, suitable for both beginners and experienced keepers looking for a decorative and useful species for their terrarium.

• Colouring: very variable and decorative "lava" pattern with strong contrast
• Size: small to medium terrestrial isopods, relatively fast growing
• Behaviour: active, often visible on the surface and easy to observe

Breeding and care

Lava Porcellio scaber require a well-aerated terrarium with a substrate rich in dry leaves, decaying driftwood and numerous hiding places. They benefit from a moisture gradient with both a wetter and a drier area, allowing them to thermoregulate and hydrate properly. A varied diet of leaf litter, rotten wood, vegetables and calcium supplements supports a healthy, stable and prolific colony.

In a bioactive setup, Porcellio scaber Lava help decompose organic residues such as shed skin, plant debris and leftover food, reducing mould, bad odours and waste build-up while improving soil quality.
