Name: Michele Roth N.E. Indiana - Zone 5b, and F (Zone 9b) I'm always on my way out the door..
I'm guessing it's one of the hives set out about a quarter of a mile from here. They usually gather up all but one or two in late fall.
I'm guessing that they leave those for stray bees (??); ones that aren't in the hives when they come out to pick them up.
