Phyllonorycter cavella (Zeller, 1846) (Figs 4B, 6B, 11 G–H) Material examined. Russia: PK, Gornotaezhnoe, forest around MTS, 43.68N, 132.15E, 224 m alt., Betula platyphylla , 23.VII.2016, 1 larva, NK541, MK 403713, deposited in INRA; same location, B. dahurica , 25.VII.2016, 1 male (reared from leaf mine), 111.1 / [11-2016-male] (Fig. 4B, 6B), deposited in SIF. Leaf mine. The mine is initially a flat elongated blotch between the two secondary veins or along the main vein on the lower side of the leaf; later gets significantly contracted, with 5–7 pronounced folds (Fig. 11G). From the upper site the leaf is significantly bent. At the late stage, the larva consumes deeper layers of parenchyma so that from the upper side of the leaf, the mine gets white (eaten area), with still some green dots (uneaten tissue) (Fig. 11H). Frass in loose grains, accumulated in the middle part of the mine. Pupation is in the mine. Trophic specialization. Commonly monophagous on Betula spp. (Betulaceae) (Ellis 2018). Records of Alnus (Betulaceae), Cerasus (Rosaceae), Salix (Salicaceae) and Ulmus (Ulmaceae) (Kuznetzov & Baryshnikova 1998) need confirmation. European subspecies Ph. cavella milleri (Povolný et Gregor) feeds on Prunus padus (Povolný & Gregor 1950). Distribution. Russia: RFE—AO, KK, PK, SO (Sakhalin Island) (Baryshnikova & Dubatolov 2007; Baryshnikova 2008, 2016), Siberia (Kuznetsov & Baryshnikova 1998), including new record for Omsk Oblast (Knyazev et al. 2018), European part; Japan, Central Asia, Europe (De Prins & De Prins 2018). Remarks. For the first time in RFE, we recorded the “green island” phenotype in Ph. cavella mining leaves of Betula platyphylla (Fig. 11H).
