Comments & ID Thoughts

We have plenty of house spiders, but none have the 4 distinct spots on the back. It was on the underside of a chair in our office (the room in the house with desks and computers). She made silk in attempts to escape, but I wanted to take a picture. I've let her go outside now, but I do have some more pictures.
