Osmia - Osmia cornifrons - Female
Arlington, Middlesex County, Massachusetts, USA

Size: about 1cm
These bees have been nesting in external window frames of my house every year. Crumbs of pollen and/or dirt appear below the entrance holes. I believe multiple individuals use the same entrance holes, but I'd have to bust open the window frame to see what's going on inside!
