Ground bee

This bee would not leave my son and me alone today when we were playing baseball in the yard.  It kept buzzing around our feet.  It looked like a ground bee, and sure enough, it landed on the ground, dug a hole in the grass, and disappeared several times!  I tried for awhile to get a picture of it - NOT an easy task - it NEVER stopped moving.  This was the best I could do with limited light and an impatient son who wanted my attention. :)  Granted, the photo is a bit blurry and noisy, but it was still too cool to not share.
