Bee fly seems like a good guess! Though Bombylius major seems to have a dark band on its wings which I can't see on your photo, so it doesn't look like that one? There are also hoverflies that mimic bees, so it could very well be one of those, too. You need to see the pattern of the "veins" on their wings to tell the different Diptera groups apart--hoverflies have a "false vein" running through the others.
