Betula pubescens, Posbank, underside


The mine begins as an inconspicuous lower surface corridor, mainly recognisable by its brown line of frass. In the next larval stage a lower-surface blotch is made, that soon develops into a tentiform mine; its epidermis turns brown. Frass in a clump in a corner of the mine. After leaving the mine the larva continues feeding in a downwards folded leaf margin, that is fixed with silk.
