The large narcissus fly is Merodon equistris. There are at least two species of "lesser narcissus fly", Eumerus strigatus and E. tuburculatus. The online literature, last time I checked, was rather vague on the subject, but it appears that other species of both Merodon and Eumerus also attack amaryllidaceous bulbs. Mary Sue asked if narcissus flies attack non-amaryllidaceous bulbs. The received wisdom is that they will but only opportunistically when they can't find anything tastier to munch on. I have seen them myself in a bulb of a potted garden hyacinth.
