Stings like a butterfly. Evolution in action.

A tropical butterfly, Hypolimnas bolina has thwarted the bacterium, Wolbachia.

Since this bacterium is carried by eggs not the sperm, it took to popping off male offspring of its butterfly host. But the butterfly has developed a resistance at genetic level, with remarkable speed, only a few decades.

Excellent. :D
