Another Parasteatoda tepidariorum, not the same one from the previous photo. This one was a couple feet away.

This one snared a millipede in its cobweb and is chowing down.

These spiders have small fangs and chelicerae, so they tend to feed by liquifying the insides and drawing it out through a small hole. This tends to leave behind a bug shaped husk when the spider is done. Other spiders with larger jaws practically chew their meals, but not these guys.
