Big spider on my door
October 15, 2009
We came home and we went “Eaahh!” There was a huge (2″?) spider on our front door. After some fiddling with our camera we managed to get a couple of half-decent photos of it. We thought it might be the California Trapdoor Spider that some others have met recently, but it’s body isn’t shiny and black and doesn’t quite look the same.

Dear Gandolfo Family
As much as we would have loved this to be a female California Trapdoor Spider, we believe it is a female Crevice Weaver Spider in the genus Kukulcania.  We found some closely matching images on BugGuide.  One of the postings on BugGuide indicates that individuals in this genus may live for 10 years.  Males are sometimes mistaken for Brown Recluse Spiders.  BugGuide has additional information.  We also are providing a link to images of the female California Trapdoor Spider, though they rarely leave their burrows.
