Eating would-be mates could lead to a bigger brood for spiders, scientists have found.

The egg cases of American grass spiders that ate their suitors were compared with those that did not in a new study of pre-copulatory cannibalism.

More spiderlings of cannibalistic mothers hatched from thicker cases than non-cannibal offspring did, it showed.

It suggests an evolutionary advantage for female spiders that may eat males rather than mating with them.

The study is published in Animal Behaviour and thought to be the first to link cannibalism with reproductive success.

I'm excited for when we can feed people clone human meat.
