The Adirondack chair, below, is in my yard. A close-up of one of the screw holes shows that a mason bee decided it was a good place to lay her eggs. A seal of mud now protects the eggs that are laid in individual compartments, end-to-end inside the hole. The fact that I provided perfectly good mason bee houses–carefully built to meet all specifications–was apparently lost on the female who chose this spot.
I probably wouldn’t have noticed this nest, except that I was sitting in that chair when it started to buzz. The chair, that is. I was really surprised when the little mason bee popped out of the side (under the arm) because she made a lot of noise. I decided to leave it alone–it’s a small nest and a big chair. There’s plenty of room for all of us.
