“I do not understand how men can kill such beauty. There can be no joy, surely, in capturing such a masterpiece of evolution, gassing it with chloroform or squeezing its thorax until it is dead, setting it on a cork board until rigor mortis is advanced then pinning it, frozen by death, in a glass-topped case, hung over with a curtain to keep the light from fading the colours. To me, this is the height of frivolous insanity.Nothing can be gained from killing a butterfly. Killing a man is a different matter.”
