Polyandry And Butterflies

This is a male fantasy, one male for forty females.....but wait it's butterflies we are talking about. The fact that female butterflies could even find mates in the presence of male-killing Wolbachia stunned scientists. In some islands there was only one male for every 40 females. One would expect this type of sex imbalance to leave females deprived of a mate, explains Hurst.“To our knowledge we’ve never heard of female promiscuity being caused by fewer males,” he says.
