from Klimesch (1977a).

mine

Oviposition probably on the base of the midrib. The mine begins as a very faint, fine, straight corridor along the midrib, that is entirely filled with frass. Later the corridor widens considerably, with irregular sides and a heavy frass line that leaves a broad transparant zone at either side. The corridor regularly alternates from upper-surface to lower-surface.
