It's official - females prefer courtship over competitiveness. And she may talk with her friends about the size of your mandibles, but it really doesn't matter.
Female mate choice and male-male competition are typical mechanisms of sexual selection. However, these two mechanisms do not always favor the same males. Researchers have investigated the complicated sexual conflict over mating in Gnatocerus cornutus, the horned flour-beetle.
Male horned beetles have enlarged lower jaws – or mandibles – used to fight rivals, and those with larger mandibles do have a mating advantage when there is direct male-male competition. But until now, it has not been clear whether the females actually prefer these highly competitive males.
