Has anyone else had alot of Bee Flies in their garden? They look like bees, they hover alot and they have a long probosis. It took me a little while to find out what they were. Some people have said they are hummingbird hawk moths but these are not around at this time of year and would be much larger. Apparently they are parasitic on solitary bees, wasps and beetles. Fortunatley they don't sting!
