The pouch is known as marsupium. Eggs hatch inside marsupium and female still keep them inside the pouch for more 3 to 4 days. After emerging from the pouch, baby ill bugs undergo few molts and then they are considered independent of their mother.

Unlike male pill bugs, female pill bugs provide maternal care to her babies as she carries them inside their pouch and after juvenile leaves their mother they still somehow stay near their mothers. Some can even make a separate tunnel from their mother or near their mother’s tunnel. If they stay inside their mother’s tunnel, then mother pill bug protects them until they are a bit more developed.
