mine
Corridor, with the frass in an almost uninterrupted line along the side. In small leaves the corridor often follows the margin, but when space is not limited, like in Hart’s-tongue Fern, it curves smoothly, not infrequently running over the midrib for some distance. Pupation mostly within the mine; the front spiracula then penetrate the epidermis.

As the pictures show, the mines can differ appreciably. Yet, when flies are reared they do show no differences (Hering, 1924a).
