Black widow Spiders are the most toxic spiders in the united states, luckily the typical life span of a Black widow spider is only 2-3 years.
Spiders don't have a pupa.

well i live there and there r daddy long legs and common spiders. i have seen a few tranchulas but most are none posionious ...There are Daddy long legs. Black widows. Tarantulas. There are a lot of other spiders. There are barn spiders. And a fast little black spider that is everywhere. It is kinda small and there are a lot of them. Most spiders here are non lethal. With the exception of the black widow. But even then if you get proper medical attention it is no big deal. I've lived here my whole life, most of the time spent on a ranch in the country.
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.
