I have not seen the mason bees in quite a while. I believe I hatched seven females from the tubes my neighbor had given me. Basically, the tubes in the high rise were covered in groups of seven, and now there are twenty-one covered cells. The blocks in the high rise are in various colors, and the bees clearly favor the darker colors, with black the most popular. There are some aqua-ish colored cells, and none were used. I think I am supposed to leave them be (heh) until late fall when I can remove the cocoons. Or technically, I can just leave them as they are, but then I would not have the opportunity to clean out all the cell blocks.

Oh, and we got our 1000th egg today. Woot
