This hoverfly (Volucella Pellucens) is also known by more friendly names - The Pellucid Hoverfly or Great Pied Hoverfly, as its abdomen is black and white (although this one is a bit creamy). They feed on the nectar and pollen of a large number of plants, and fly from May until October. They are quite a large fly (one of the largest) - with a body length of 13-17mm and wingspan of around 15mm.
