Leaf-mine: Broad lower surface mine which generally starts at the leaf apex.The mine is somewhat irregular in depth. Frass in irregular black-green, frequently melted grains, mostly along the edges of the mine. Larva solitary. Pupation generally internal (Nederlandse bladmineerders). Larva: The larva is described by de Meijere (1928) and Nowakowski (1973). Puparium: Flat, deeply segmented, shining metallic bluish-black; posterior spiracles projecting through the epidermis, widely separated, each on a conical projection with 3 bulbs (Spencer, 1976: 192, 193 (fig. 336)).
