I haven't seen one like this here before. I'm wondering if she's a recently molted one of the usual residents:
|On the wall over my bed. Not invited in.|
|The resident sowbug deleter. Not welcome in bed, either.|
I'll send her photo in to BugGuide for an ID. (Update: sac spider, yellow sac or similar. And very pregnant.)
*One kitten has gone to her new home; three to go soon. Then maybe I can get some sleep.
