Comments & ID Thoughts

Spider was the size of a U.S. quarter. It moved at a slow crawl crossing asphalt road. Trapdoor spider?

Whoa, he’s a radiant fellow! I’m not well acquainted with Mygalomorphae … but this looks to me like it might be a California Trapdoor Spider (Bothriocyrtum californicum). They’re typically a lot darker than this, black even. I have to wonder if he’s freshly molted. Maybe someone will be along eventually who knows them better than me with more insight.
