Leaf-mine: A long, narrow, upper surface mine widening at the end and with frass in conspicuous black strips. Pupation normally takes place on the ground but the puparium not infrequently remains in the exit slit at the end of the mine (Spencer, 1976: 370, 371 (fig. 645)). The mine is illustrated in British leafminers and Nederlandse bladmineerders.     Mines of Phytomyza agromyzina on Cornus. Images: Brian Pitkin Larva: The larva is described by de Meijere (1926). Puparium: Yellowish-brown; posterior spiracles each with some 17 bulbs (Spencer, 1976: 370).
