The bees I've noticed so far this year have been bumble, mason, sweat (where sweat bee = any smallish bee that I can't be troubled to sort out from the other smallish bees), and a few honey. I think. I haven't spent as much time gardening this spring as I usually do, so I haven't seen as many bugs as usual. Haven't seen any ladybugs copulating, for instance, and I usually see a fair amount of that.

Most of the bees I've seen have been the big guys, more bumblebees than mason bees. I haven't seen any of the flies that look like honeybees yet this year.
