"The redback is one of few arachnids which usually display sexual cannibalism while mating. The sperm is then stored in the spermathecae, organs of the female reproductive tract, and can be used up to two years later to fertilise several clutches of eggs"

  One wonders how such a system would ever evolve - but I have read that at least in Praying mantids, which also display sexual cannibalism, the sex organ of the male frequently breaks off during mating - blocking the female and preventing her for a time from breeding with any other males. After that, the male essentially loses his interest in life and so the female snacks down - but at least the male ensures that the offspring for a while at least will be his. Posted 6 years ago

The Redback spider

The redback spider is a species of venomous spider indigenous to Australia. It is a member of the cosmopolitan genus "Latrodectus", the widow spiders. The adult female is easily recognised by her spherical black body with a prominent red stripe on the upper side of her abdomen and an hourglass-shaped red/orange streak on the underside.
