Is that the Banded Argiope (Argiope trifasciata)?

Nope, the body is silver, kinda fuzzy looking.

Looks like a Banded to me, too...did you find it dead?

Hope you didn't kill it.....

I'm voting for the banded argiope, too. After the females have finished building that large egg sac and have filled with chock full of eggs, they shrink up and die.

These spiders do have a silvery, furry cephalothorax.
