Insect and Spider Identification: What kind of spidey is this?, 1 by kittytown

I found this guy (or gal?) right next to our front door-we live in Milwaukee, WI. It has a smaller/wheel shaped web and a body size around a dime. It was feasting on a former fuzzy bumble bee. When we got in closer to get a picture he quickly scampered off. He then came back about 2 minutes later, removed his bug from the web and is now sitting with his dinner in the bush. My boyfriend is terrified of spiders and wants him removed ASAP-I think he is awesome and rarely get such interesting visitors in the city (don't worry-I will protect him from the "non-spider folk"). Please help me identify this guy!
