There are always many inexplicable phenomena in the world of animals, especially in the mating of animals, which can be said to be very interesting, cruel and romantic all kinds of animal courtship behaviors exist, many of which can be said to be more cruel than higher animals, and some more romantic than higher animals.
For example, the "love in the air" of bees, male bees die after mating, and the female mantis of the mantis eats the male mantis after mating has made people very curious, with the development of society, many phenomena that we once thought were solved by science, such as the male mantis in order to obtain love to sacrifice himself as food to the female mantis, which has now been completely overturned.
In fact, like praying mantises will have their own as a "snack" to the partner of the insect and many friends do not know, that is, the competitive golden spider, literally we know that this is a spider, spider belongs to a variety of insects, and spider love is also very interesting, different species and different sizes of spiders, its lifestyle is not the same, even in the courtship behavior, is also diverse, gift courtship, duel courtship, sacrificial courtship and so on courtship methods can be found in the spider world.
Regarding the issue of the male spider being eaten by the female spider after mating, it is actually a more controversial issue, in the process of male mantis and female mantis mating process The male mantis is eaten This process is considered to be confirmed as the hunting behavior of the praying mantis, many friends may immediately blame the female competitive golden spider for eating the male competitive golden spider when the competitive golden spider mates on the hunting behavior, in fact, it is not unreasonable to say so.
Taking the scientific explanation of mantis mating as a reference, there are 2 doubts in the mating of the competitive golden spider, which is explained in more detail in the spider naturalism, according to the indoor observation of the competitive golden spider, the probability of male competitive golden spider being eaten by the female competitive golden spider is as high as 90%.

This statement is actually similar to the situation of mantis mating, according to the introduction of "Spider Naturalism", the male spider that is eaten when the competitive golden spider mates has two characteristics, one is that the male spider is mostly eaten when mating twice, and the second is that the eaten spider is an old male spider, with poor physical strength and slow movement, these characteristics actually meet the characteristics of being hunted by female spiders, so it is not surprising that they are eaten, which is similar to the mating of mantises.
<h1 class="pgc-h-arrow-right" data-track="7" > second: active devotion</h1>
On this point, it has to be said that it is also possible, because there are two key words mentioned here, one is that the mating male spider is the male spider that has mated for the second time, and the second is that the spider that is eaten is the elderly male spider, from the perspective of reproduction, the male spider has actually completed the genetic inheritance when the first mating is carried out, and the secondary mating is actually an additional reward for many male spiders, and it is also possible that these spiders are willing to give themselves as a gift to the female spider after completing the genetic task.
As for the old male spider is more likely, for the old male spider, if you want to compete with the young male spider, there must be no advantage, in the spider world, male spiders in order to compete for partners to kill each other is not uncommon, if according to this way of competition, the old male spider must not have an advantage, want to let the female spider accept the old male spider, the best way is naturally after mating the old spider to sacrifice themselves as food to the female spider.
This seems to be a more cruel process, but because the old male spider has not lived long, it can reduce the lifespan a little, and let its genes get more inheritance before death, which seems to be justified from the animal's genetic instinct.
