Porcellio Scaber (Orange)

The Orange Isopod (Porcellio scaber “Orange”) is a bright and hardy colour morph of the common rough woodlouse. Bred in captivity for its vivid orange tones, this morph combines the durability and strong breeding habits of the species with bold, eye-catching colour.

Scientific Classification

• Scientific name: Porcellio scaber

• Family: Porcellionidae

• Common name: Orange Isopod

Appearance

• Medium-sized, elongated body

• Distinct rough, textured exoskeleton

Natural Background

The species Porcellio scaber originates from Europe but is now widespread across the world, commonly found in:

• Gardens

• Woodland leaf litter

• Compost heaps

• Beneath logs and stones

The Orange morph is a selectively bred captive variety and is not typically seen in wild populations.

Behaviour

Active and resilient, Porcellio scaber are efficient detritivores that feed on:

• Decaying leaves

• Rotting wood

• Vegetable scraps

• Organic debris

They are quick-moving and rely on speed and hiding rather than conglobation for protection.

Invertebrate Keeping

Orange Porcellio scaber are popular among hobbyists because they are:

• Hardy and adaptable

• Fast breeding

• Suitable for bioactive enclosures

For optimal care, provide:

• A moisture gradient (humid and drier areas)

• Abundant leaf litter and cork bark

• Good airflow

• A reliable calcium source for healthy moulting

With proper conditions, they establish colourful, thriving colonies that add both function and visual appeal to naturalistic terrarium setups.
