Black Willow Spiders

It was recently believe that Female Black Widow spiders would chase down and eat whoever the mated with. Not males.  Now it is believed after a study that was conducted that Male Black Widow spiders are more likely to eat their mate even before eggs are laid. It was more likely for young male widows to eat older female spiders. A study shows that widow spiders mating is chosen very carefully. It is dependent on age. They eat unprefered mates just as much as females do. It is a knew look on the mating stystem of theses spiders.
