Porcellio laevis
Porcellio laevis (commonly called the swift woodlouse, dairy cow isopod, or smooth slater in Australia) is a species of woodlouse in the genus Porcellio. As the species epithet laevis as well as the vernacular name "swift woodlouse" suggests, the species is capable of quick bursts of speed when provoked.
This species of woodlice is distinctively large, appearing up to 20mm long with a smooth dorsal surface. The males can be identified by their long, spear-shaped uropods. Porcellio laevis has a smooth dorsal surface, which separates its visually from many other species of the Porcellio genus.It is commonly kept as a pet due to its somewhat easy care requirements and the variety of color morphs available. The species is easy to keep and can be easily established in a terrarium within a few weeks. "Dairy cow isopod" is a commonly used name for a readily available piebald strain of the species.()
