This 2007 photograph, captured by CDC biomedical photographer, James Gathany, depicted a female black widow spider, Latrodectus mactans, as she was in the process of spinning her web upon a tree branch. You'll note the characteristic red hourglass located on her inferior abdominal surface, which can vary in coloration from yellowish, to shades of orange and red, and at times, can even be white. The female's body is an overall shiny jet-black in color. This spider was found on a farm, here in the state of Georgia.
