Mason bee update...
I now have 14 filled tubes of mason bees! I started my colony by purchasing 6 tubes (in march of this year).
I have a chair by their nest boxes and I sit and watch them several times a week.
They are incredibly industrious!
They have bounced off my head a couple times because I was in their flight path, but, they totally ignore me and get back on track LOL! They don't get excited, even when my nose is 6 inches away from their tubes. I am really enjoying having them in our orchard!
