That is pretty awsome about the bugs.
I also had a 'pet' spider this year. She made a huge web from the tree branch all the way to the grass, and even attached it to a bush. Was she trying to catch animals? lol. She is gone now, but it was fun to see her through the glass window. So egg sacs, huh? Does that mean im going to have a bunch of those huge scary spiders? I hope not, ugh.
This is all coming from someone who owns a giant african millipede! Here's a pic of Millie. Don't worry, they're vegetarians.
