mine
Unusually long, interparenchymatous, therefore yellowish corridor that remains of equal width throughout its length. (In some plants with thin leaves, like Cirsium oleraceum the mines are not interparechymatous but either full-depth or alternating upper- and lower-surface).The mine makes few curves, and hardly any u-turn, causing the mine to usually occupy the entire length of a leaf. Frass in two rows of grains along the sides. Pupation within the mine, in a lower-surface pupal chamber; the front spiracula penetrate the epidermis.
