I have these little blackish bees in the outside of the house, I guess maybe
6mm long or so. I think they must be pretty common because I've seen them so many places before. They get into the little squarish holes between panels in the wood siding. They seem indifferent to my presence & pretty much just go about their business. Do the bees make the holes themselves or do they just exploit the flaws? Seems like a bee would chew a rounder shape. Are they very damaging?- posted
