Porcellio aff. laevis 'Dairy Cow'

Porcellio aff. laevis ‘Dairy Cow’ – Large Black-and-White Isopods

Creation Cultivated ‘Dairy Cow’ is a large, highly active isopod recognized for its bold white body and irregular black spotting.

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

Dairy Cows are famous for fast colony growth, an exceptionally strong appetite, and highly visible feeding behavior.
