Osmia bruneri, f, Wy, lincoln co, back
Here is a series of male and female western glinting Osmia. There is a whole clade of Osmia that have thrust aside the drab dark colors of their Osmini kin for fresh look of maximum iridescence. That iridescence trends across greens and blues and purples with males often more on the green side. Here are some from the National Parks of Wyoming...both Fossil Butte and Yellowstone. More spectacular than Old Faithful, I would say.
