gal: Eieren worden afgezet op de ongeopende bloemen. De uitkomende larven infecteren een zich ontwikkelende vrucht, waarin zich tot 100 larven kunnen bevinden. Geinfecteerde vruchten worden door en door zwart, en vallen af wanneer ze ca 2 cm groot zijn. De larven zijn geelwit en kunnen springen. Univoltien; de overwintering als larve in de grond.
