Porcellio aff. laevis 'Milkback'

Porcellio aff. laevis ‘Milkback’ – Cream-Backed Isopods

Creation Cultivated ‘Milkback’ is a large, smooth-bodied isopod recognized for its pale cream-to-white back framed by darker gray or brown sides.

Although commonly sold as Porcellio laevis, the Milkback hobby line is more accurately treated as Porcellio aff. laevis because its exact species identity remains unresolved.

Milkbacks combine distinctive two-tone coloration with active behavior, a strong feeding response, and dependable colony growth.

Commonly Used For
