New York Times: “Scientists have found other species in which males encourage their own cannibalism. One remarkable twist on this strategy is seen in a species of orb-weaving spiders. The males suddenly die as they mate. The male’s death may be a strategy for preventing other males from mating with the female. In death, its sexual organ becomes stuck in the female’s receptacle. Even if she feeds on the rest of his body, the organ remains behind, preventing her from receiving more sperm.”
