I think you might have seen a leaf-cutter bee. They're used here in southwestern Idaho a lot to work alfalfa seed crops. They are wonderful because they aren't agressive, their sting is not painful like a honeybee and they will hybernate (or maybe they just die and the larvae hatch in spring) in boards that you can put in a barn to overwinter requiring no food or care at all. They also don't produce honey, so the farmers can just get their fields polinated without having to have someone bring in honeybees. I searched on the WWW and found a few hits on leaf-cutter bees. Here's one: http://clay.agr.okstate.edu/alfalfa/webnews/pol-01.htm This one has pictures: http://www.pollination.com/IPSalfbee.html See if you think that's it.
