Taurus Mason Bee (Osmia taurus), taken March 18, 2025, in Georgia, US
Hard at work...admiring a rock? I'm honestly not sure what these guys are doing, possibly removing fine sediment from the rocks? There are dozens flying along the stones on the edge of my creek banks. The best guess I have is that they're collecting fine sand or dirt to do their "mason" work with. They're quite shy, but if I sit still enough, they'll come check out the rocks near me!
