Crickets that can mate every 18 seconds
Apparently, these little guys suffer from the syndrome we call "beer goggles" when observed in humans.
From BBC news:
"Pre-copulatory song usually acts as a barrier to cross-species mating because females aren't attracted to the song of another species," explained Dr Vahed.
But alpinus males do not bother with any such formalities: they will apparently leap on any unsuspecting cricket - male or female - without introduction."
