You are now enlightened.
The act of dismounting is one of the most dangerous times for males during copulation, for it is at this time that females most frequently cannibalize their mates.
This is at least the third time you have put incorrect information on the forums, you have no credibility and now you are ignored for spreading bad information.
I am aware that you cant trust a wiki but it does its job sometimes. Here is a larger portion of mating practices for a mantis.
Sexual cannibalism is common among mantises in captivity, and under some circumstances may also be observed in the field. The female may begin feeding by biting off the maleGÇÖs head (as they do with regular prey), and if mating has begun, the maleGÇÖs movements may become even more vigorous in its delivery of sperm. Early researchers thought that because copulatory movement is controlled by a ganglion in the abdomen, not the head, removal of the maleGÇÖs head was a reproductive strategy by females to enhance fertilisation while obtaining sustenance. Later, this behavior appeared to be an artifact of intrusive laboratory observation. Whether the behavior in the field is natural, or also the result of distractions caused by the human observer, remains controversial. Mantises are highly visual organisms, and notice any disturbance occurring in the laboratory or field such as bright lights or moving scientists. Research by Liske and Davis (1984)[13] and others found (e.g. using video recorders in vacant rooms) that Chinese mantises that had been fed ad libitum (so that they were not hungry) actually displayed elaborate courtship behavior when left undisturbed. The male engages the female in courtship dance, to change her interest from feeding to mating. Courtship display has also been observed in other species, but it does not hold for all mantises.
The reason for sexual cannibalism has been debated, with some considering submissive males to be achieving a selective advantage in their ability to produce offspring. This theory is supported by a quantifiable increase in the duration of copulation among males who are cannibalized, in some cases doubling both the duration and the chance of fertilization. This is further supported in a study where males were seen to approach hungry females with more caution, and were shown to remain mounted on hungry females for a longer time, indicating that males actively avoiding cannibalism may mate with multiple females. The act of dismounting is one of the most dangerous times for males during copulation, for it is at this time that females most frequently cannibalize their mates. This increase in mounting duration was thought to indicate that males would be more prone to wait for an opportune time to dismount from a hungry female rather than from a satiated female that would be less likely to cannibalize her mate. Some consider this to be an indication that male submissiveness does not inherently increase male reproductive success, rather that more fit males are likely to approach a female with caution and escape.[14][15]

I will throw my hat in there. I am an opinionated fanboy that believes in the game, I try not to troll and I try to provide at least a small paragraph justifying my stances. I try to use $3 words even though I am a terrible speller. I make grammar errors and sometimes use logical facilities to help "prove" my point. I usually only post on my main unless I am writing a post in the Intergalactic Summit part of the forums. I am active but a terrible player, I have been here from the beginning and enjoy being bad at the game. I like Graphology, Sci-FI and regular science. I am on Twitter @BurlenDaire.
