After vacating the mine, the larva moves to the leaf tip (often on the neighbor leaf), bends it downwards creating a triangular cone in which it continues feeding ( Fig. 10H). Pupation is external, in a cocoon on the low side of the leaf.  Trophic specialization.Mainly oligophagous on Salicaceae:  Salix,  Populus,  Chosenia, rarely found on Betulaceae ( Betula), Myricaceae(  Myrica gale), Fabaceae(  Robinia pseudoacacia) (Baryshnikova 2016; De Prins & De Prins 2018; Ellis 2018).  Distribution. Russia: RFE—AO, KK, PK, SO, KamK; Siberia, European part ( Baryshnikova 2008, 2016); Japan, China, Korea, Mongolia, India, North Africa, Central Asia, Asia Minor, Caucasus, Europe, Canada( De Prins & De Prins 2018). 2313474863 VI Russia 431 53.98 Skovorodino 644 123.93 17 18 1 2313474872 [216,655,908,935] MK, SO Russia 17 18 1 2313474890 2017-07-11 MK Russia Island 69 46.97 Gagarin Park 672 142.75 Yuzhno-Sakhalinsk 17 18 1 Sakhalin
