Leaf-mine: Upper side blotch mine beginning with a deeper, almost full depth corridor. Frass grains not in thread-like pieces, irregularly scattered. In the large, later blotch indistinct primary and secondary frass lines are found; the frass accumulated in the middle. The mine is illustrated in British leafminers and Nederlandse bladmineerders.
