What kind of spider is this?
Found in the garden in New Brighton, here is the Twin Cities. Web and spider appeared in the morning. This fly was caught by noon. That evening, the web and spider disappeared. I could literally see the spider spinning the fly around with its legs to find the best place to start eating.

You have a garden orb spider. They are harmless. Something must have caught the web and destroyed it so she moved on. Here is a little more info about them. http://bugguide.net/node/view/1972
