Corridor, up to 30 cm in length, descending from the leaf tip. The larva eats the spongy parenchymatous pith. Regularly also bands of green tissue are consumed, which betrays the presence of a larva. The frass is whitish, felty, and becomes coarser all the while down the mine. In the higher parts of the mine frass-free stretches may occur, The final instar larva lives freely, feeding on young leaves.
