If there are a lot of bees on the blooms it is probably a male Rosa setigera plant. It doesn't set hips, does it?

Actually, this one DOES set hips. The female flowers would have to be pollinated in the first place in order to set said hips, eh?
***My other photos in autumn of this rose clearly show the hips and fiery foliage if you'd like to check those out.

Yes, if there are hips, it would be a female plant

I anticipated as such, but the thing I'm stuck on regarding your statement that the plant I have "could be a male because a lot of bees visit it" is this:
How could the female flowers not attract bees/other pollinators and still become pollinated and then set hips?
I'm just trying to understand your thought process on the claim made because to me it seems illogical. It doesn't make sense for the female plants to not attract pollinators but yet somehow still get pollinated. Am I missing something? I mean no snark or disrespect, but I require an explanation for this claim that seems at odds with facts, nature, and rationale.

The female plant is also visited by bees, but not as much as the male plants.
It is so strange that this has been the subject of a scientific article. See: "Cryptic dioecy and insect pollination in Rosa setigera Michx. (Rosaceae), a rare plant of Carolinian Canada" by Kevan et al., 1990.
I chanced upon the dioecy after seeing that a replacement R. setigera we got for our garden, wasn't as attractive for bees as its predecessor.
