Video: Praying mantis still mating

While the male mantis is drunk doing "that", the mantis bites the mate's head.

For every male mantis, every mating opportunity is like a mortal gamble. In lovemaking, female mantis can eat mates to get more nutrients for its future children. If the love takes place when the mantis is full, the male mantis's ability to retain life will increase. Conversely, if the mantis is hungry, it seems that the male mantis has done a suicide job when mating.

The male mantis in the video continues to pump sperm into the female mantis body after its partner chews its head. When the mantis receives enough sperm, it kicks the partner's body down. The male sacrifices to make sure the opportunity is made. Its death helps the mantis be able to provide nutrients to the children.
