Well, there's five black widows that reside in the United States. There's the Black Widow, the Northern Widow, the Western Widow, the Brown Widow, and the Red Widow. The Red Widow is very crazy looking found rarely in, and found mostly in, Central Florida. The Brown Widow actually began in Florida, and has now spread from Carolina, all the way across the south, to California. The rest of the widows, most predominately are found, in their different respective regions, North and Western, black widows across the South. But they can be found as far North as Maine.
