@Da_Gut Blueberry bees are smaller than bumblebees but look like them. Male bumblebees are half the size of females, though, so could be confused with blueberry bees. Could be the situation you describe.I think there are even other similar-looking bees, and it is fairly common for bee species to "defeat" the pollinating strategy of a flower. The NC Extension has a pretty decent guide to our native bees, but it also impresses upon you the many types and similar features.
