Can anyone ID this Spider?

I snapped this thing on a plant in my backyard.

I looked at a few spider identification sites but I'm not coming up with anything.

It's fairly big, to me at least, about the size of a quarter.

Can anyone tell me if it's anything I should worry about?

Nope, looks like a species of orb spider. Eats a lot of harmful insects...

Thanks. I appreciate the ID.

i believe that is an orange orb weaver. great spider for gardens. gets rid of unwanted insects.

So, yes, you should worry if you're an insect. Awesome shot.

That is one cool but creepy looking spider.

You used to play Everquest didn't you? The way you asked the topic brought back memories.
