I read that the male black widow was much smaller than the female. I recently discovered that the "mutated breed of black widow" around my house was just a male, but couldn't believe it because all the male black widows I've seen are just as big if not bigger than the females, and they're all really big. I have a serious widow problem! If the male black widow is supposed to be so much smaller than the female, why are these so large? Can they be more/less poisonous with size?
