Porcellio Scaber (White)
White Isopods (Porcellio scaber “White”) are a striking captive-bred colour morph of the common rough woodlouse, prized for their pale, almost ghost-like appearance. Their bright white to creamy colouration creates a dramatic contrast against dark substrate, leaf litter and naturalistic enclosure décor, making them an excellent choice for both bioactive enclosures and dedicated isopod collections.
Combining the hardiness and adaptability of Porcellio scaber with an unusual pale colour morph, White Isopods are a popular choice for keepers looking for an attractive, active and productive terrestrial isopod.
Scientific Classification
- Scientific Name: Porcellio scaber
- Genus: Porcellio
- Family: Porcellionidae
- Common Name: White Isopod
- Morph: “White”
- Type: Terrestrial Isopod
Appearance
White Isopods have the characteristic elongated body shape and textured exoskeleton associated with Porcellio scaber, combined with their distinctive pale colouration.
Key features include:
- Solid white to creamy-white colouration
- Medium-sized elongated body
- Rough, textured exoskeleton
- Dark contrasting eyes
- Clearly segmented body
- Active, elongated appearance
- Does not roll into a tight ball
The pale colouration is associated with this captive-bred morph and gives the colony a particularly distinctive appearance when viewed against darker substrate and leaf litter.
Natural Background
Porcellio scaber is a widespread species originally associated with Europe and is now established across many parts of the world.
The species is commonly found in environments containing moisture, shelter and decomposing organic material, including:
- Gardens
- Woodland areas
- Leaf litter
- Compost
- Beneath logs
- Under stones
- Decaying vegetation
The White Isopod is a captive-bred colour morph selected for its distinctive pale appearance rather than the typical darker colouration seen in wild Porcellio scaber.
Behaviour
White Isopods are active, hardy and highly effective detritivores. They spend much of their time exploring the enclosure, moving through leaf litter and searching for decomposing organic material.
Their natural diet includes:
- Decaying leaves
- Rotting wood
- Dead plant material
- Vegetable matter
- Organic debris
Unlike species that curl into a defensive ball, Porcellio scaber generally relies on movement, speed and concealment when disturbed.
Their active behaviour also makes them an excellent choice for keepers who enjoy observing their isopod colonies.
White Isopod Care
One of the main advantages of Porcellio scaber is its adaptable nature. White Isopods can be suitable for both newer and experienced isopod keepers when provided with appropriate environmental conditions.
A suitable enclosure should include:
- A moisture gradient
- Moist and drier areas
- Good ventilation
- Plenty of dried leaf litter
- Decaying hardwood
- Cork bark or other hides
- Organic-rich substrate
- A reliable calcium source
A moisture gradient allows the colony to move between areas of different humidity and select the conditions they require.
Avoid keeping the entire enclosure constantly saturated. Good ventilation and access to drier areas are important for maintaining a healthy colony.
Feeding
Dried leaf litter and decaying hardwood should form the foundation of the White Isopod diet.
Additional foods can be offered periodically, including:
- Specialist isopod diets
- Vegetables
- Suitable protein sources
- Other appropriate organic foods
A continuous calcium source should also be provided to support healthy exoskeleton development and moulting.
Bioactive Cleanup Crew
White Isopods are an excellent addition to bioactive terrariums and naturalistic vivariums.
As detritivores, they help process decomposing organic material such as:
- Fallen leaves
- Dead plant matter
- Decaying wood
- Organic debris
This makes them both a visually striking display species and a functional bioactive cleanup crew.
Their bright colouration can also make them particularly easy to spot against darker substrate, allowing keepers to observe natural colony activity more easily.
Breeding & Colony Growth
Porcellio scaber is well known for its ability to reproduce successfully in suitable captive environments. With consistent conditions, plentiful food, adequate shelter and an appropriate moisture gradient, White Isopods can establish healthy and productive colonies.
Providing abundant leaf litter, decaying wood and calcium helps support continued colony growth.
As the colony develops, keepers can enjoy observing different generations moving throughout the enclosure and contributing to the ongoing cleanup process.
