“Mason bees (genus Osmia) are a type of native bee that?s quite common throughout most of the U.S. They are usually a little smaller than a honeybee, and typically metallic blue or blue-black in color. They get their name from their habit of nest-building, which is to seal off the cells where they lay their eggs, with a mortar-like application of mud.” https://www.gardeners.com/how-to/about-mason-bees/8198.html
My first mason bees have laid their larvae in the tubes! Very excited to hell out the local population!
