My redbud is in full bloom as is a few other plants and bushes. They are covered in black and yellow big bees; natives I believe. I could only get one half decent picture. Funny bees, they would fly around me really, really fast making a big noise if they were annoyed; I just froze and then they went back to business. Bees from my hive were not on these same plants. I am curious as to why; are the big bumblebees keeping them off or do they just prefer other plants?
