Leaf mine.

Full-depth wide linear mine on mature leaf in young instars and full-depth ophiogenous blotch mine in old instars (Fig. 9 O – Q). Frass is thread-like, deposited along the middle line of the mine in young instars, but in old instars along meandering larval trajectory, scattered throughout the mine. The fully grown larva exits the mined leaf, falls to the ground, and pupates underground.
