The prevalence of cannibalism in some species of Latrodectus has inspired the common name "black widow spider". The female's venom is at least three times more potent than that of the males, making a male's self-defense bite ineffective.

Research at the University of Hamburg in Germany suggests this ultimate sacrifice strategy has evolved to promote the survival odds of the offspring; however, contrary to popular belief, females of some species rarely eat their partners after mating and much of the documented evidence for mate cannibalism has taken place in laboratory cages where the males could not escape
