Very nice photo Darren What you have there is a Syrphid Fly...Family Syrphidae (Syrphid Flies). a lot of them look like bees and wasps. A good way to tell in your picture is the shape and size of the antenna. Flies usually have small antenna and two wings (generally) http://bugguide.net/node/view/196/bgimage
