Column of 5 cells each around a cm wide between 2 bricks on the wall of a garage and concealed behind a wooden bird nestbox. Each cell has grey and brown walls of a kind of mortar-like material and contains a yellow substance apparently pollen packed on one side or the other and with a single translucent off-white egg protruding from it. I found an unusual bee which I identified as perhaps a species of Osmia on the same day in my house.
