I believe it to be sp. mellifera, but since I cannot find similar markings on the many illustrations in my field guides, I am not certain. Hope a member can help.
CLOSED: Is this bee an Apis mellifera
Not a bee at all, but a male flower/hover fly in the family Syrphidae - looks like an Eristalis sp. - see http://www.commanster.eu/commanster/Insects/Flies/SpFlies/Eristalis.rupium.html for an example.
Eristalis tenax is indeed a possibility - see http://www.glaucus.org.uk/Hoverfly025.jpg for an image. However, I also know that there are other European species in this genus that can have a similar appearance - see http://en.wikipedia.org/wiki/File:Eristalis.horticola.male1.jpg for an example.
Thanks Flapdoodle for the info. Several possibilities indeed. I'm just starting to get familiar Syrphidae. I'll probably go stir crazy in the process.
