The Dairy Cow Isopod (Porcellio laevis) is one of the most popular and energetic species in the bioactive hobby. Named for their distinct white bodies and irregular black "cow-like" spotting, these isopods are prized not just for their appearance, but for their incredible work ethic.
They are a large, fast-moving species that acts as a powerhouse "Clean-Up Crew" (CUC). Unlike smaller, more shy species, Dairy Cows are highly active throughout the day and are known for their voracious appetite, making them perfect for large enclosures with high-waste inhabitants like large lizards or frogs.
Key Features and Benefits:
Exceptional Cleaners: They rapidly consume leaf litter, animal waste, and decaying organic matter.
High Activity Levels: One of the most "visible" isopods, often seen exploring the terrarium surface even during the day.
Rapid Breeders: They establish colonies much faster than most other species, making them a cost-effective choice for large bioactive setups.
Nutritional Supplement: Their high calcium content makes them an excellent occasional supplemental snack for insectivorous reptiles.
Hardy & Adaptable: They thrive in a wide range of humidity levels, though they prefer a moist "hydration station" within the enclosure.
