I figured they were egg sacs but I wasn't sure if they were from a spider or not.

I'm not familiar with that quicksilver spider and I'm trying to read more about them right now.

Interesting how they take over the web. There was another spider in there with the big Silk Spider last month. She was eating a bee and he kept charging at her, like he was trying to steal it, she finally dropped it. I thought maybe it was a male spider. I found a picture I took of them.

I was very surprised to see her gone from the web one morning. There was a big hole in the middle of it, I thought maybe a bird had got her. Maybe it was some kind of thief spider.

Not seeing many of this type egg sac on the internet, but will keep looking, I'm not real familiar with the spider sites. Thanks for your help so far.
