A male Springbok praying mantis looking for a hook up doesn't have to worry about a female stealing his heart away. There is, however, a very good change she'll bite his head off, and he knows it. Indeed, 60 percent of sexual encounters between Springboks -- one of nearly 2, mantis species across the globe -- end in males being eaten as snack. All male mantises show extreme caution when approaching a prospective partner.

Male praying mantises have found a way to avoid getting eaten during sex - Science

Research finds species of female praying mantises who eat males after sex produce greater number of eggs than those who do not. Death by cannibalism might seem like a high price to pay for a fleeting moment of passion, but male praying mantises are doing it for the kids, new research suggests. Scientists have discovered that female praying mantises who eat their mates after sex produce a greater number of eggs than those who do not, with the bodies of the ill-fated males used to aid their production. The authors say the new study backs up a long-mooted theory that males could have evolved a behavioural trait of self-sacrifice to boost their reproductive success. If, by dying, the male can boost the number of offspring produced by one female, the theory goes, it could outweigh the downsides of missing out on future conquests. Published in the journal Proceedings of the Royal Society B by researchers in the US and Australia, the new study reveals how scientists unpicked the influence of cannibalism on the production of offspring in the praying mantis Tenodera sinensis, by tracking what happened to male ejaculate and bodily tissues after mating.

Male mantises fight females to mate - but they get eaten if they lose

If you find yourself outside this time of year, you might come across one of the world's more intriguing insects: praying mantises. Despite their saw-like arms and alien eyes, they pose no threat—unless of course you happen to be an insect, gecko, or hummingbird. The animals have also spent all summer hunting and growing, repeatedly shedding their exoskeletons as they reach lengths of up to half a foot.

By Karina Shah. Female praying mantises are famous for attacking and cannibalising their mates during or after a sexual encounter, but evidence is emerging that some males attack too, and that winning a fight is crucial for successful mating. Sexual cannibalism is common amongst praying mantises. Typically, the female is the aggressor, which encourages males to approach the female carefully and cautiously when mating. They wrestle and sometimes seriously injure the females in an attempt to mate and avoid being eaten.
