Most interesting ,Mark. I have a patch of Narcissus pseudonarcissus here in Seattle, and the Narcissus fly doesn't touch it either. I always assumed their is some particular chemical make-up of the tissues that doesn't appeal. Some Narcissus varieties are magnets for the fly, and others apparently have some compound or composition to repel, or, at least not interest this pest.
