Do mantis die after laying eggs?

Yes, many female mantises die shortly after laying their eggs. This phenomenon is known as sexual cannibalism, where the female may consume the male after mating or, in some cases, even during the egg-laying process. However, not all species exhibit this behavior, and some females can survive for a time after laying their eggs. Ultimately, the life cycle of mantises involves the female sacrificing herself for the sake of her offspring.
