Spider

I found the spider and web while working in the yard today. I have no idea what kind it is, but would love to find out. I don't think it's a black widow, but maybe in the same family.

I had never gotten very close to them, but the orange abdomen stands out. I hadn't noticed the bluish body until I got this close up (won't do it again!)

These are fairly common in the yard, but I hadn't seen these here before Hurricane Katrina, so maybe they flew in on the wind and tides.

Update: My sister found an ID on the web: It is an Orchard webweaver(Not poisonous!) Thanks Jan!!
