1858年，威廉·法尔（WilliamFarr）首次发现了这一效应，他写道，寡妇和鳏夫的死亡风险比已婚同龄人高得多。

The effect was first noted in 1858 by William Farr, who wrote that widows and widowers were at a much higher risk of dying than their married peers.

令人庆幸的是因黑寡妇叮咬死亡者相当罕见。黑寡妇攻击性不强，只有自卫时才咬人，比如有人意外地坐在它们身上。

Fortunately, fatalities are fairly rare; the spiders are nonaggressive and bite only in self-defense, such as when someone accidentally sits on them.
