All through intercourse, feminine praying mantises generally tend to kill their companions with a decapitating chopping blow that may make a samurai proud. However as this surprising new video presentations, simply because a male doesn’t have a head doesn’t imply he nonetheless can’t get it on.

Everything of this pretty new Deep Glance video approximately praying mantises is value staring at, however the nasty industry begins across the three:00 mark. The feminine chops off the male’s head throughout the dating level, however like the attractive insectoid zombie that it’s, the male—sans head—keeps to mate with the feminine, mounting her and turning in the sperm in an effort to fertilise her eggs.

As defined within the video, the male’s frame continues to be being managed via nerves in its stomach, and “it could nonetheless get the process performed.”

Biologists discuss with this conduct as sexual cannibalism, and the mantis feminine doesn’t do that out of spite or as a few more or less mindlessly random act. A State School of New York-Fredonia paper from ultimate yr confirmed that men who get fed on by way of their associates are in fact at a reproductive merit.
