About
The Narcissus bulb fly, scientifically known as Merodon equestris, belongs to the family Syrphidae and its larvae feed on the bulbs of narcissi, eventually leading to their death. The adult fly feeds on nectar from flowers and resembles a bee, for which it’s often mistaken. Females lay eggs at the base of narcissus leaves in spring. After hatching, the maggot burrows into the bulb to feed. The patterns and hair colouration of the Narcissus bulb fly exhibits a wide range of variation.
