https://bugguide.net/node/view/31430 Cool! When I was a kid my dream was to did up a dinosaur or this species of spider. I lived in Connecticut, the dinosaur dream was actually possible, but not the spider.


Nice find. The only trap door spider I have ever seen is the California trap door spider.
Bothriocyrtum californicum. None of these with the flattened abdomen.


You almost had the name. “truncata” means cut off or shortened. It’s cute that you gave it a bath for the photo. There have been a few times when I thought I chopped a spider or insect with my shovel, but was relieved to learn it wasn’t my fault, that’s just what the critter looks like. I’m glad your grandsons got to experience this spider.
