The mine is a flat roundish white blotch with a short preceding epidermal tunnel (which however, may be indistinct), most commonly on the lower side of the leaf (Fig. 12 C). At the later stage the mine is contracted, with few weak folds on the epidermis covering the mine. Frass in loose grains accumulated in the middle part of the mine. Pupation in the mine, in a light cocoon. Trophic specialization.
