Leaf-mine: An unusually long, narrow, whitish linear mine, frequently following a vein. Numerous larvae can occur together in a single leaf which can be completely eaten out. Pupation external (Spencer, 1972b: 74 (fig. 247); Spencer, 1976: 438, 439 (fig. 766)). The mine is illustrated in Nederlandse bladmineerders and British leafminers. Mines of Phytomyza lappae on Arctium sp. Image: Willem Ellis (Source: Ellis,Nederlandse bladmineerders) Larva: The larva is described by Sasakawa (1961) and Dempewolf (2001: 194). Puparium: Black; posterior spiracles each with an irregular ellipse of 20-28 bulbs (Spencer, 1976: 438).
