Narcissus flies

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.
