The mine begins as a narrow corridor, somewhere halfway the leaf; it ascends towards the tip, doubles, and descends to about the starting point. Meanwhile the corridor has widened to about half the width of the leaf. Most frass is accumulated as an elongate dark mass in the oldest part of the mine.According to Traugott-Olsen & Nielsen part of the frass can be ejected through an opening in the lowest part of the mine. The mine is greenish white and quite conspicuous. Pupation external; pupa ina a loose spinning (Bland, 1996a; Traugott-Olsen & Nielsen, 1977a).
