Asplenium scolopendrium, Belgium, nr. Dinant © Paul Fontaines

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.
