Scientists believe that maritime earwigs practice this behavior in order to make their clutch maintain the size that best optimizes their investment.

In this case, the mother will often eat the youngest child, which serves to shorten the total time she spends caring for the young.

As she optimizes the childbearing process, the amount of energy she has to spend on her remaining children increases, as does their chance of survival.
