Why Do Female Praying Mantis Eats Male?

Why Do Female Praying Mantis Eats Male

When talking about praying, there are some reasons why the female praying mantis eats its male counterpart.

First, the male becomes more effective in mating when decapitated. This is in connection with the use of nerve tissues in the abdomen when making copulatory movements.

Thus, mating can still go on with the intact abdomen. Unique to mantises, there’s a nerve center in the male’s brain that doesn’t allow mating if the female is not clasped yet.

Another reason is due to impulses. When a temperamental female is threatened or surprised, it immediately turns into the male and devours its head. Sexual cannibalism is common among other animals like scorpions and spiders.

To some praying mantis species, it’s a common ritual that doesn’t need to be reasonable. Female mantis will likely do it if there’s a food shortage.
