I think this is a cobweb spider Parasteatoda tepidariorum

There are some similar Therrids, but I’ll agree with the most common. I have been confused this year by the many colors and patterns, sizes, and behaviors of Parasteatoda – the ones I’ve observed have been really variable. One put her egg sacs in a broken Paper Wasp hive.

They are such pretty little.jewels aren’t they. For the ID I was going by something I remember reading ages ago and can’t find again….. the very dark line on her butt facing us and the parallel lines at the lowest point facing us. It might even have been a way to distinguish Parasteatoda imports from native UK therids in which case it wouldn’t be valid to differentiate US ones.
