Osmia aglaia
Oregon berry bee
Osmia aglaia is a solitary mason bee native to the western United States. It is commonly known as the Oregon berry bee due to its specialized role as a pollinator of brambles, particularly raspberries and blackberries. The species exhibits metallic coloration and nests in pre-existing wood tunnels. Adults are active in late spring, coinciding with Rubus bloom periods.
