When any spider makes the egg sack for its babies does it stay in there? Particularly were wolf spiders?

Question

I found this big white cacoon looking thing on a rock and my dad pulled really hard to open it and I daw what looked like a brown were wolf spider and a bunch of white things that looked like eggs. I didn't know if the big spider was one of the babies (it seemed too big) or the parent.

Answer 1

I have never seen a were wolf spider.  Do they drink blood like human werewolves.  The egg sac of a wolf spider is bigger than the spider.  She stays with the eggs and when they emerge they ride on her back.
