This summer I had 5 spiders living around the yard. The first 3 i spotted were larger than the last 2 that showed up. The larger ones disappeared from their webs several weeks ago but the 2 smaller ones stayed with their webs. A couple days ago they were not on the webs. I figured they were finished for the year because of the cooler weather that moved in. This morning I saw one had moved a few feet and had an egg sac hanging near by. After seeing this I went to look where the other one was, and found an egg sac but didn't see the spider. it may be hidden somewhere close by though. Hopefully next year I have many more of these to look at.
