The work of Israeli scientist Jutta Schneider of Israeli Ben Gurion University shows that killing children is not just about mammals and birds. In fact, the spider Stegodyfus lineatus, which inhabits the desert of Negev, kills its young.
The reason for killing their children is very simple. The female spider, when it has offspring, ignores the male and abandons it. However, when the male spider eats its offspring, the female wants to make more offspring and approaches the male.
