We’ve all heard of the dreaded Black Widow – no not the Marvel comic super hero, but the infamous spider with a deadly bite that is mainly known for it’s sexual cannibalism. Not only do black widow spiders have a venomous bite (with females being up to three times more venomous than males), but the female really lives up to her “black widow” namesake as she will often eat her male partner after mating. However, a new study has shown that the tendency to consume a potential mate is also true of some types of male spider. The study by Lenka Sentenska and Stano Pekar from Masaryk University in the Czech Republic finds that male spiders of the Micaria sociabilis species are more likely to eat the females than be eaten.
