This spider is an orb weaver and I had one hanging around in my garden tool shed for a couple months last fall. Got quite a few shots of it. Most spiders are quite harmless.
Great shots, particularly like #1. That's not a reason to stay in doors at all, as Jerry said, most of them are harmless. If I had something like that in my yard, I would be camping out with my 100mm macro and grabbing as many shots as I could. Just curious - what happened to #5?
