larva in opened mine; upper surface of the mine

mine

Lower surface tentiform mine that occupies an entire leaflet; lower epidermis strongly folded. Fully developed mines are strongly inflated and the leaflet is so completely folded over the mine that the latter becomes practically invisible. In this stage the larva has consumed also all tissue in the roof of the mine, making the mine thereby very conspicuous. The pupa in a cocoon that consists of a loose lining of the walls of the mine.
