This is a hoverfly. It is not a bee but a type of fly and it does not sting. It feed on pollen. They sometimes hover for few seconds and that is the only time when it is possible to capture them in flght. I took this as the fly hovered for about 4 to 5 seconds. I manualy focused on it and had just enough time to take one shot in both times that the fly hovered near me.
