Steatoda triangulosa?
I think I found it. She looks just like the Steatoda triangulosa.

Steatoda or Asagena
Is there any chance you can get a shot of the full dorsal pattern?

Spider
Hi Lynette.

I added a few more images. You can see her size as compared to her most recent dinner, a housefly. As you can see, she's very prolific and is eating well. She is inside my house and I only noticed her because of her pile of food leftovers that are piling up below her.

A fifth egg sac higher up had just hatched when I took the first picture on the 19th. It looks like she has made 2 new egg sacs since then.

I don't mind leaving her where she is as long as their bite isn't dangerous to us. She's doing a fine job catching flies.
