I usually like to get my bugs identified at bugguide.net. I haven't done that with this one. This is one of four spiders that we kept in the garage this past summer. They were big and kept growing bigger. They grew so fast and so big we did not have the courage to kill them. You were at risk if you walked under their web at night (they are night hunters) because they could quickly drop down on your head or shoulders. Want to see this guy even bigger? Click on the photo. A new window or tab will open for you and take you to the photo's Flickr page. On the top left of the photo is a drop down menu labeled "Actions." Click that and select "View all sizes." Then you can choose to see it as big as you can stomach!
