How to identify (and misidentify) Brown Widow The brown widow spider, Latrodectus geometricus, is not native to the United States. For decades, it lived only in peninsular Florida in the U.S. but in the first decade of the 21st century, it spread remarkably quickly, is now found from Texas to South Carolina and is well established in the urban areas of Los Angeles, San Diego and surrounding suburbs. In the western United States, accurate identification of this spider can be difficult. The brown widow is a tan spider with a series of white stripes.
