黑寡妇蜘蛛的英文介绍

Latrodectus is a genus of spider, in the family Theridiidae, which contains 31 recognized species. The common name widow spiders is sometimes applied to members of the genus due to the behavior of the female of eating the male after mating, although sometimes the males of some species are not eaten after mating, and can go on to fertilize other females.[1] The black widow spiders are perhaps the best-known members of the genus. The injection of neurotoxic venom latrotoxin from these species is a comparatively dangerous spider bite, resulting in the condition latrodectism, named for the genus. The female black widow's bite is particularly harmful to humans because of its unusually large venom glands; however, Latrodectus bites rarely kill human beings if their wounds are given medical treatment.
