Mimic of a bee

This is actually a fly ( Hoverfly) trying to look like a bee,
However contrary to a be it has only 2 wings instead of 4 and the antenna are very short.
It its aver y useful fly in the gardens, because it fertilizes the plants.
It is hard to photograph, because it does not long stay in one spot, It hovers and can fly sideways. This one must have really liked the nectar, because it sat long enough for me to take this picture.
