Steatoda triangulosa
The adult female triangulate cobweb spider is 1/8 to 1/4 inch long , with a brownish-orange cephalothorax and spindly, yellowish legs. The round, bulbous abdomen is creamy in color, with parallel purply-brown zigzag lines running front to back. This distinctive pattern sets it apart from other theridiids in its area. The triangulate cobweb spider is known to prey on many other types of arthropods, including ants (including fire ants), other spiders, pillbugs, and ticks. It preys on several other spiders believed to be harmful to humans, including the hobo spider and the brown recluse. The egg sac of the triangulated cobweb spider is made from loosely woven silk, and is about the same size as the spider itself. Each egg sac contains approximately 30 eggs.

I managed to catch this little guy this morning & get a few macro shots. I've uploaded more photos including one for size comparison.
Thanks C Snydes! I think I will submit it to bugguide to see if they can ID it for me.
Interesting markings on the abdomin, is small because it is young or just a tiny species? I would imagine it is a relation of a button spider (Black widow family)
