Porcellio Scaber (White)

The White Isopod (Porcellio scaber “White”) is a striking captive-bred colour morph of the common rough woodlouse. Known for its pale, almost ghost-like appearance, this variety stands out dramatically against darker substrates and is highly popular in bioactive and display enclosures.

Scientific Classification

• Scientific name: Porcellio scaber

• Family: Porcellionidae

• Common name: White Isopod

Appearance

• Medium-sized, elongated body

• Characteristic rough, textured exoskeleton

• Solid white to creamy pale coloration

• Dark eyes often contrast against the pale body

• Does not roll into a tight ball

The white coloration is the result of selective breeding and is not typically found in wild populations.

Natural Background

The species Porcellio scaber is native to Europe but is now widespread globally, commonly inhabiting:

• Gardens

• Leaf litter

• Compost heaps

• Under logs and stones

The White morph has been developed in captivity and maintained for its unique aesthetic appeal.

Behaviour

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

• Decaying leaves

• Rotting wood

• Vegetable matter

• Organic debris

They are more likely to rely on speed and concealment rather than curling into a ball when disturbed.

Invertebrate Keeping

White Porcellio scaber are well-suited to both beginner and experienced keepers due to their:

• Strong adaptability

• Reliable breeding

• Tolerance of a range of humidity levels

For best results, provide:

• A moisture gradient within the enclosure

• Plenty of leaf litter and hiding spaces

• Good ventilation

• A calcium source to support healthy moulting

With proper care, they form thriving, visually striking colonies that serve as both effective clean-up crews and standout display isopods.
