Western Black Widow - Latrodectus hesperus - female

Western Black Widow - Latrodectus hesperus - Female
Santa Cruz Island/Prisoners Harbor, Santa Barbara County, California, USA
June 21, 2008
Size: body 7-8mm +/-
This was on the ocean beach inside a large broken gastropod shell. I don't know much about spiders, so don't want to assume that this is a Black Widow because of the red markings.

My ID
was just based on the location. I am not an expert and can't guarantee it's not a different widow, just to let you know.

Subadult female.
The dorsal red markings indicate this is probably an immature female (they lose their dorsal red markings, usually, as they age). Not sure if any other widow species exists in your area.
