Black Widow

White spider with hour-glass dots on back
March 15, 2010
Found on a dead rabbit, amid the fluff of it’s shed fur. The rabbit had been under an old tin bucket and when I lifted it up, this spider was on the fur.

Immature Black Widow Spider

Hi Colleen,
This is an immature Black Widow, probably a Western Black Widow, Latrodectus hesperus.  The immature spiders often have patterns on the back which become a solid glossy black as the spider matures.
