Better picture, plus a pic of the egg sack. Still no clue what it is but its only 1 1/2 inches long. No fiddle that i can see on its back. The egg sack is about the size of a pea. Caught in the house and has a tunnel in the web. Poisonous or not, I will not kill it. period. The very least i'll release it in the woods. But I do want to watch the little ones hatch caus it's something I've never seen in person (even though from what I'm told it looks like a scene from a horror movie lol) Any oppinions would be greatly appreciated. FYI: There are no holes in the lid so nothing can escape. It's in an old mayonnaise jar I just open the lid once every few days to let in fresh air.
