latrodectus - Latrodectus hesperus
El Cajon, San Diego County, California, USA
October 9, 2011
Size: 1 inch
This one crawled out of a light fixture that I had been disassembling and handling after I laid it on the ground. I'm guessing female because of the size and a younger spider because of the coloration.
