This image was captured on the webcam this morning at 9:45am. It was overcast, about 54oF, so the bees are sitting at the nest entrances waiting for the sun, or for the temperatures to warm up enough to fly. Most of them are males; you can see the yellow spot on their faces. They are using the tunnels as shelter for the night, but they do not make a nest like the females. Note the bee sitting on top of the emergence box.
