mine (from Sasakawa, 1971a)
The first part of the mine is a 6-11 mm long gallery that usually starts in the top of the leaf. Descending towards the leaf base the gallery widens, in the end occupying the full width of the leaf. Secondary feeding lines are present. Frass in gradually larger granules. Generally one mine per leaf. Pupation external, but most of the times the puparium sticks on the leaf on only 2-6 mm from the exit slit.
