I observed this Honey Bee sized fly visiting flowers but unlike the Honey Bees that visit the flowers very briefly landing, this one stayed somewhat longer. At least long enough to allow me to get 2 images of it. I'm calling this a fly rather than a bee because of mainly the head which is fly-like instead of bee-like although the thorax is bee-like. The abdomen is similar to a bee but has black bands rather than golden like a bee would have. There does appear to be pollen sacs on the top side of both the thorax and the abdomen near the wing bases.
