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.
