I think it's a type of orb weaver. I have one just like it in my backyard. We've had a lot of rain, and for the past few days it's been curled up in a few leaves it sewed together. There's a link below to the bug guide website.

I have a bunch of those in my back yard. Makes for a very yucky walk around the gardens LOL. I don't like spider webs in my hair or anywhere else on my body.
