Well, bees will be bees, and they'll go wherever there are flowers to collect nectar and pollen from, regardless of whether or not city officials and neighbors want them. Yesterday while I was weeding our front flower garden and putting down wood chips, I ran into 4-5 of these little buggers flying around...
Some quick online research revealed that these are Andrenid Bees. They are small, native, solitary bees that build nests in a small, pencil sized hole they dig in the ground. Here's some info:

I've known about solitary bees before. In fact, I remember some bees digging tunnels in the sandbox at my parents' house when I was a kid. I've also known that you can build houses for various types of solitary bees, but never did much research. So I did a little last night. It seems that many of these native bees are even more prolific pollinators than honey bees! Plus their homes are super easy to build, inconspicuous, and probably wouldn't bother the neighbors in the city too much. Maybe I'll take up a project soon and build a house for some bees here. Then I can be a city beekeeper as well!
