This is my first posting in the macro section of the forum although I have posted a few photos in the microscope section. This photo was handheld with a Fuji 6900z in my garden back in May 2003. The bee's most striking feature is it's white face which should make it easy to identify - nevertheless to date I have been unable to put a name to the species - so any help would be much appreciated. The tongue sheath was very obvious even to the unaided eye.
