Hi all, I saw a big, brown and dark brown striped spider in the juniper tree in front of my house today. Big, maybe the size of a half dollar coin from leg tip to leg tip. Was wondering if it's dangerous or benign? If it poisonous and I should be worried I'd like to take care of it but if it's going to feast on the bagworms and other pests, I'll let it be. If I could find a picture I would but since I'm not sure what to google, I'm hoping someone here knows.... Thanks!
