Similar to calico cats, calico isopods are mottled with black and orange. They're one of many color variations of Porcellio scaber, the common rough woodlouse, also known as the roly-poly.

Common rough woodlice are temperate species. They can subsist in a wide range of living conditions. They do well in lower humidity ranges than most other isopods, making them great candidates for bio-active desert set-ups.

They're not the most prolific isopod you can culture, but they'll do quite well after becoming established under appropriate care.
