Leaf-mine: A distinctive mine with a short linear section at the beginning, then winding and forming a secondary blotch and finally a short straighter end section. Pupation internal or more normally the puparium falls to the ground (Spencer, 1972b: 96 (fig. 96), 97; Spencer, 1976: 324 (fig. 738). The mine is illustrated in British leafminers and Nederlandse bladmineerders.
