Larvae feed within leaf mines. After hatching, larvae enter the leaf tissue on the underside of leaves. As the larvae switches from sap feeding to tissue feeding the mines become visible on the upperside of leaves. Mines appear as pale yellow-green regions, usually with folds in the leaf. Pupation occurs in the mine.
