The most vigorous Narcissus and other related bulbs respond to these flys
as if they had been twin scaled, an increase in bulb numbers results. N
bulbocodium is certainly not immune here, nor is L aesivitum, but they both
survive the fly and enough mature bulbs survive to put up plenty of
flowers, with extra vegetative increase!
