Abstract. A little-known scathophagid fly is reported infesting the flowers and scapes of Narcissus poeticus growing in the Italian Central Apennines (AQ). This insect bores through the flower bud and lays an egg on the tepals. Both pistil and scape parenchymatous tissues provide the larva with nutrition, and the hollow stem a safe site for its metamorphosis. Infestation by this insect prevents the ovules from being fertilized as the larvae feed on the tisues in the style and so prevent the growth of pollen tubes.
