Душераздирающая история о сексе и жизни насекомых
During mating in bugs called seed beetles, the females violently kick the males because the males hurt them with their spiky penises. Everyone's assumption (including our own) was that the females kicked males to end the mating sooner. But our research showed that an earlier onset of kicking and doubling in kicking duration does not change copulation duration.
Тhe researchers also found that among the females that could kick, those that kicked for longer periods of time died sooner after they laid their eggs than those that kicked for a shorter time. But the females that kicked for longer did not lay any more eggs than those that kicked for shorter periods.
This is good for males, because it is in his best interest to be kicked longer if his partner dies sooner, and therefore reduces the likelihood that she will mate with another male.
