folding-door trapdoor spider

5638    Hi there,   My name is Jake and this photo was taken on April 3, 2016 in Cowichan Bay, BC – on the east coast of Vancouver Island. This spider was approximately an inch long. I uncovered it while weeding a flower bed. It was very docile and I could see a pulsing movement through a clear area on its back. I would love an idea of what kind of spider it might be. (Obviously not at baby tarantula 😉

This looks like a female Antrodiaetus pacificus, a folding-door trapdoor spider in the family Antrodiaetidae; see for an image. Ed Saugstad, retired entomologist; Sinks Grove, WV.
