'Cold on the back' of the female mantis chewing on her partner's head while mating

Female mantises are often described as "evil seducers" by attracting males to "get close" and then eat them after mating. This is a real thing, recorded by scientists.

The video above shows that even before the male can have sex , the female rushes in and attacks and beheads her partner.

However, even in the " headless " state , the mantis man completed the mating process without any difficulty.

According to zoologists, the reason they can do this is because the mantis brain is located in the head , controlling behavior, while the ventral ganglia controls the movement of copulation.

Male mantises are usually much smaller in size than female mantises.

After all, this is not necessarily a meaningless action. Because when eaten by a female, the male is more likely to deliver the genetic code to the egg through each part of their body.

This is a way of showing that the male mantis is willing to make sacrifices to ensure a source of nutrition for the next generation.

The reason it chooses the head to eat, is because the mantis head contains the most protein.

According to one study, females who eat their mates often lay more eggs, with an average of 88 eggs compared with 37. However, if a male can mate more than once, that also increases the likelihood its inheritance.
