What Is It??

This afternoon I looked out my window and saw the most interesting organism... On first observation I thought it was a large spider.  However, after looking at more closely I noticed that it had only six legs - NOT a spider.

I think I may have discovered a new species!  =]

Have you ever seen anything like this?  If you have, and you know what it is, please comment and share your wealth of knowledge!  For now, I think I'll call it the "Manna" bug ("What Is It") =)
