How do you know if a woodlice is going to have babies?

You can tell if a woodlice is going to have babies by observing the presence of a brood pouch, or marsupium, which is located under the female's body. If you see a female woodlice with a visibly swollen pouch, it indicates that she is carrying developing embryos. Additionally, you might notice small, developing woodlice visible through the pouch, signaling that she is close to giving birth.
