　　The brown widow spider became established in Southern California in early 2000 and has become part of the local spider family in urban Los Angeles and San Diego. The brown widow spider is continuing its expansion in Southern California and could possibly move northwards into Central California.

　　The brown widow is suspected to have evolved in Africa although it was first described from South America, which adds confusion as to where it might have originated.

　　It is a tropical and subtropical spider having established populations in Hawaii, Florida, parts of Australia, South Africa and Japan.

　　In North America, the brown widow was restricted for many decades to the Florida peninsula.

　　However, around the year 2000, it started showing up in other Gulf Coast states.

　　Brown widows are now known from Texas to Georgia and South Carolina.

　　The brown widow builds its web in protected sites around homes and in woody vegetation with branches. Some typical sites selected by brown widows for web building are empty containers such as buckets and nursery pots, mail boxes, entry way corners, under eaves(屋檐), storage closets and garages, undercarriages of motor vehicles that are stationary for long periods, and the undersides of outdoor furniture. They choose places that are more exposed than sites chosen by black widows and therefore appear to be at higher risk for interactions with humans as far as bites are concerned.
