ABSTRACT

A fruit fly delivers his sperm in a toxic cocktail that consigns his consort to an early death. A female dung fly, caught in a scrum of eager suitors, is ignominiously drowned in a cowpat. A spider eats her mate in the very act of copulation. Dramas such as these epitomize the battle of the sexes. Or do they? What is that notorious battle really about? And how can we tell it from life's many other conflicts?
