A great breeder, and rival in size for P. hoffmanseggi. There is some dispute about whether these might be grouped into the same species, but the jury is still out. This is another isopod that is very active during the daytime, and they definitely like conditions that are drier than most. We keep ours on soil mixed with powdered calcium carbonate, and provide wood and cement (broken cinderblock) for shelter. Though not a continual breeder, they are extremely prolific--litters of 30 or more are not uncommon!
