Any of several black spiders in the genus Latrodectus with a venomous bite that is rarely fatal to humans. Black widow species are found worldwide, with three living in North America. In Australia it is called the redback. The females are shiny black, usually with a reddish hourglass-shaped design on the underside of the spherical abdomen and with a body about 1 in. (2.5 cm) long. The black widow preys on insects. The male, about one-fourth the female's size, is often killed and eaten by the female after mating (the source of its name).

The social status of widows has been an important social issue, particularly in the past. In families in which the husband was the sole provider, widowhood could plunge the family into poverty, and many charities had as a goal the aid of widows and orphans (often, not children without parents, but children without a contributing father). This was aggravated by women's longer life spans, and that men generally marry women younger than themselves, and by the greater ease with which men remarried.
However, in some patriarchal societies, widows were among the most independent women. A widow sometimes carried on her late husband's business and consequently was accorded certain rights, such as the right to enter guilds. More recently, widows of elected officials have been among the first women elected to office in many countries (e.g. Corazon Aquino).
There were implications for sexual freedom as well; although some wills contained dum casta provisions (requiring widows to remain unmarried in order to receive inheritance), in societies preventing divorce, widowhood permitted women to remarry and have a greater range of sexual experiences. The Wife of Bath in Geoffrey Chaucer's Canterbury Tales refers to having been widowed five times, permitting her greater sexual experience.
In some other cultures, widows are treated differently. For instance, in India there is often an elaborate ceremony during the funeral of a widow's husband, including smashing the bangles, removing the bindi as well as any colorful attire, and requiring the woman to wear white clothes, the colour of mourning. Earlier it was compulsory to wear all white after the husband was dead, and even Widow burning (sati or suttee) was practiced sometimes. However in modern-day culture this has gradually given way to wearing colored clothing. Sati practice has been banned in India for more than a century. The ban began under British rule of India owing to the persistence of social reformer RajaRam Mohan Roy.
In other cultures, widows are required to remarry within the family of their late husband; see widow inheritance. This started as a custom to ensure that no widow could be kicked out of her home and face a life without financial provision, but it can also be used to keep money within the family. In addition, it is an important factor in the transmission of HIV within certain communities, e.g. the Luo, and is being challenged on human rights grounds.
