I found this while sweeping outside. We home school, so any new spider we find, we scoop into a jar and try to identify it. Then we let it go.
We live in Oregon. Wasn’t sure if it was a trapdoor or funnel spider.
Thanks!

Folding Door Spider

Hi Kim,
Thanks to the multiple views you have provided, we strongly believe this is a Folding Door Spider in the genus
Antrodiaetus based on images posted to BugGuide.  There are several families of Trapdoor Spiders, and Folding Door Spiders are distinguished from the Cork-Lid Trapdoor Spiders and the Wafer-Lid Trapdoor Spiders, but BugGuide doesn’t really explain the distinguishing features.  It is nice to hear about your home schooling tactics, but we must caution you that here at What’s That Bug?, we are not experts and we do not have any formal entomological training, nor have we ever taken any college level courses in Arachnids.  We are artists who are trying to promote an understanding and appreciation of the lower beasts and their importance to the web of life on our fragile planet.  For more accurate identifications, you should seek assistance from your local natural history museum.  There is much misinformation on the internet, and our humble website is no exception.
