There are more than 350,000 beetles living on the earth, and their breeding methods are varied and varied. When mating, the most tragic fate is the female weevil. The male weevil’s penis has a terrible thorn that often damages the female during mating. Researchers have pointed out that larger thorns can make male weevils win in the “genetic arms race,” and the most sharp and sharpest weevils often produce more offspring.
Since it is known that mating is an extremely painful process, why does the female weevil agree to mate with males? The explanation given by scientists is that the elephant worm lives in an extremely dry area, and semen can supplement the female weevil with urgent needs. Water. After getting enough water, the female’s mating interest is greatly reduced. When they are short of water, they are full of hunger and thirst for mating.
