Fenusella wuestneii (Konow, 1894)

Salix viminalis, Veessen
mine
Oviposition on the leaf blade. From there a quickly widening corridor, ending in a full depth brownish blotch that frequently overruns the initial parts (Viramo, 1969a). Initially the mine expands towards the leaf tip, later it descends towards the base (Buhr, 1933a, 1941a). Pupation shortly after the larva has vacated the mine.
host plants
Salicaceae, narrowly monophagous
Salix viminalis.
According to Liston (2007b) references to other Salix species (caprea, cinerea, elaeagnos, herbacea, purpurea, silesiaca, triandra) are dubious. References to Salix lapponum apply to Fenusella septentrionalis.
