Western Black Widow - Latrodectus hesperus - Female
Tubac, Santa Cruz County, Arizona, USA
September 12, 2020
While this spider seems a brighter brown than would be expected in L. hesperus, I believe that the shape of the hourglass (anterior portion wider) is consistent with the description on Rick Vetter's page (Internet Reference #3 on the BG info page for L. hesperus). Also, the spider is very shiny, consistent with hesperus. Anyway, this is a confusing ID, so please correct if needed. And I would request an explanation why so I can get it right next time!
