Black and Yellow Argiope

Came across this interesting looking spider while at Mission Espada (there were at least two of them located in the garden just in front of the mission). The wikipedia page has a lot of good information, as does a Google search for "Texas Garden Spider" or "Argiope". Although several articles say the female spiders can grow to about an inch, this one was roughly an inch and a half in size (it was a little smaller than the the width of my camera lens).
