Sand bees are funny. They just kind of lollygag around in the air almost always flying low to the ground. Now, if bees bother you, it is kind of unnerving to have these guys swarming all over the place. I don't know if they are really bees or wasps or just some flying insect, but, they do live in the sand which was quite a surprise. Once the sandy soil went away, so did the critters.
