It is kind of desperate when a girl has to forcibly hold down a guy with spikes to get some action! But it goes to a whole new level when ‘she’ is the one bringing the ‘penis to the bed’!

But the team led by Kazunori Yoshizawa, an entomologist at Hokkaido University in Japan and Rodrigo Ferreira has stumbled upon the first case in the world where the females are the aggressors with the penetrating organ and the males the choosy ones with a vagina!

While role reversals are not uncommon in the animal world, this is without a doubt a whole new high. Four new species of Brazilian cave-dwelling bugs belonging to the Neotrogla genus have sex-reversed genitalia that see the female species using a ‘fully functional’ penis to draw the sperm from the males.

Females in three of these four species have a penis that contains a spine, while the fourth one has a strong curved penis that matches the curved ale chamber.

The team also uncovered other startling facts regarding the mating habits of these insects. For starters the couples mated for well over 50 hours on an average and that is an exceptionally long time among any known animals.

Also, the spikes among the female penis clench onto the male chamber so hard that when scientists tried to separate them during copulation, they ended up ripping the male insect apart!

While the reason for the reversal of genitalic roles in the species is not fully explained yet, biologists speculate that it is due to lack of nutrients in these deep dark caves.

The female not only gets the sperm from the male, but also vital nourishment in the form of fluids, which help it in the carrying the young.
