What does the black widow do to the male spider after reproduction?

After mating once the female Black Widow is pregnant for life. The females have a special receptacle that stores sperm for as long as she lives. When her eggs mature, the female spins a silk ball and deposits the eggs in the ball.(up to 400 at a time) after those tiny black widows exit the ball and scatter then the female Black Widow begins the process over and over until she dies. They can live for years. How may egg balls and young she will produce in her lifetime depends on how much food she captures.
