Recluses are reclusive
You're unlikely to ever see one in broad daylight. They're also completely different in just about every way from this spider. Not that I blame you- there's an astounding amount of misinformation about recluses even in a great many otherwise reliable sources.

See the Brown Spider (Loxosceles) guide page for more information.

Yeah, I reall didn't think it was a recluse, but after searching under "california desert spiders" recluses and tarantulas were all I could find, and I started seeing very very slight similarities to some of the recluse pictures. I wasn't sure what it was. But like you said, there is alot of misinformation out there!

BTW, this one was found at about midnight, crossing the road in Joshua Tree on a cold night. We stopped and I took some flash photos. He seemed very slow and dosile (probably from the cold ?) - Now that I know he was a trapdoor, I wish I would have tried to follow him a little longer...

Thanks Ben and Gordon! I think that's right.

I did an image search for the Bothryocyrtum californicum and found this picture which seems very accurate.
