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??
