not what it seems

What make photography magic is it slows you and makes you look and see.  When you pick up the camera and walk you start paying attention to color, light, shapes, textures,  and what is around you.  Today  I saw lots of new little holes by the septic and thought ants. There were lots of tiny bees buzzing around which made me realize these were not ant holes, but  bee holes. They have dug out of the sandy soil.  When I saw a bee emerging from a hole I tried to get a shot,  but they jumped back into the hole.  I sat and waited.    What kind of bee I don't know. So did a bee, wasp, yellow jacket lay eggs last fall and they hatched out in spring?  Have I always missed this? 
So much going on around us that we miss.
