I believe this is a female grey sac spider. I find them often but not as much as the yellow sac spiders.
I’m not getting any results when I search for grey sac spider. Is it the same as a broad-faced sac spider?
Try “gray” sac spider. It is a name for Cheiracanthum mildei, which our site calls a Long-legged Sac Spider. I have a photo of one that is gray instead of yellow. I’ll post it soon. It is a different species than the Broad-faced Sac Spider.
Oh, cool! Good to know.
