Salix viminalis, Brummen, 11.x.2007: leaf rolls
The mine begins with an unusually long lower-surface epidermal corridor that often follows the midrib for some distance, but finally turns towards the leaf margin, where a small blotch is made of up to 1 cm in diameter. The blotch initially is fully epidermal, but later the larva starts consuming parenchyma, silk is deposited, and the blotch begins to develop into a somewhat contracted tentiform mine. In the end the mine is vacated and the larve continues living freely under a leaf fold that has been fixed with silk (in poplar), or in a leaf tip that has been turned into a cone (in Salix). Pupation in a shiny cocoon at the underside of the leaf.
