Leaf-mine: An irregular linear mine, which in small leaves can form a secondary blotch. Long, upper-surface corridor, winding through the leaf and frequently crossing itself; in small leaves often a secondary blotch in the end. Frass in short strings and pearl chains. Pupation outside the mine (Bladmineerders van Europa). The mine is also described and illustrated in British leafminers. Bellis perennis Solidago gigantea Mines of Liriomyza pusilla Images: Willem Ellis (Bladmineerders van Europa) Larva: The larva is described by Dempewolf (2001: 150). Puparium: Orange; posterior spiracles each with 3 bulbs.
