Welcome to the Spiders of the Californias website.  This is a project under development as time allows.  The intent is to eventually provide you with photos and information relating to the spiders of San Diego and Imperial Counties, California, USA, as well as Baja California and Baja California del Sur, Mexico.  Narrative will initially be shown in English and later translated into Spanish for users on both sides of the international border.  Suggestions and corrections can be addressed to Jim Berrian at
