Are you all kidding me?? :)
Where in your link is stated that bees would have only two wings??? Citation, please!
... this one has only 2 wings and ...
... and it has FOUR! Do you really want to tell a biologist whose father is a beekeeper how many wings bees have?
Did you read my discussion with @barski? It seems it causes huge problems for inexperienced insect photographers to differentiate between bees and hoverflies. I wasn't aware of this problem before I created this community.
As you obviously don't believe me, just read here.
I think this is the same one on my picture, isn't ?
Of course it isn't the same!
Did you check the pattern on the back of the fly in your picture and compare it with the photo in the link which I gave you, yes or no? If I give you a link, please check that link.
Why in the end I always must show you the pictures because you just don't open the links??

You said "Are you all kidding me??"
Not at all ! ... I know you are an expert on insects and me not at all , I just wanted to understand a little bit more on differences. I looked the links you gave me, but it is not easy at all when we are not familiar on biology.
But I took note of your advices :-)
Just found this new post on hoverflies : https://peakd.com/hive-101587/@dannewton/insect-portrait-project-hoverflies
Don't worry, I guess determining insect species is not easy for you, but can you imagine that it's really very time- and energy-consuming for me to discuss every second day with various users the differences between bees, wasps and hoverflies? :-)
Did you for example read the link concerning the number of wings in bees? It's four, and your hoverflies have only two. That alone is enough to exclude the option it could be a bee. Then the post from @dannewton shows a haltere very well, right?
Did you also see the triangle-shaped pattern on the back of your #6 and compared it with the photo I showed you?
I hope all that helped you a little bit.
