The female black widow is shiny black usually with a red hourglass shape or two triangles together on the underside of her round shaped stomach. She hangs upside down so it is easy to see the color. The black widow spider weaves a tangled web. It is poisonous to humans. When its web is disturbed it will use its poison. They have a red spot on their stomach. Black widows like to live in hot areas. The black widow is the best of the cob web weavers. A black widow spider's poison is ten times more powerful than the rattlesnake's bite.
