Spider

I don't know much about insects yet, but if my guess is correct I'd say it looks like a cross spider or possibly an Orb Weaver (actually I think they are both the same, cross spiders are Orb Weavers... drats I don't remember). I have plenty of Orb Weavers/Cross Spiders in my neighborhood, all different sizes and colors. But what type of Orb Weaver/Cross spider that one is... I really don't know.

You could go and try asking at What's that bug [link] or try your luck in finding it in the BugGuide archives [link]

But remember, I'm just guessing it's a type of Orb Weaver/Cross spider type. Good luck and awesome shot!
