Leaf-mine: Initially a linear mine running towards apex of leaf which then turns back and develops into a blotch in the area of the mid-rib (Spencer, 1972b: 37, fig. 114A; Spencer, 1976: 110, fig. 177;). Larva: The larva is described by de Meijere (1925) and Dempewolf (2001). Puparium: Reddish-brown; posterior spiracles each have 3 bulbs (Spencer, 1976: 110).
