Specimens in nature


An oval tentiform mine on the underside of a leaf, most of the time between two secondary veins, and mainly situated near the basis of the leaf. No distinct longitudal central fold, but some faint folds close to each other. The upperside of the mine turns to yellow, at first with a green island in the centre, but in the last stage completely yellowish. The dark frass is concentrated in a corner of the mine.
