Tiny spider mom and babies

Theridion sp.
I have these tiny spiders living on the brickwork of my front porch.  They build their tiny webs in the recesses of the mortar between the bricks.  They have very round abdomens with a white "moustache" on top of a mottled pattern.

Baby spiders feeding with Mom
Yesterday, I noticed that one tiny spider mama had a new bunch of super-teeny tiny pink babies.  And what was even more interesting was that they seemed to be feeding communally on some kind of dead bug.
This sent me to the internet, where after some searching, I learned that there is a genus Theridion that does this.

Here is another mama-to-be.  Her egg case is bigger than she is!
