Russia : SO , Sakhalin Island , Yuzhno-Sakhalinsk , Gagarin Park , 46.96N , 142.75E , 69 m alt., Betula platyphylla , 11.VII.2017 , 1 larva, NK623 , MK 403679 , deposited in INRA. Leaf mine. The mine is similar to Ph. cavella but with hardly any folds visible. Up to three mines per leaf were recorded in RFE. At later stages, the leaf is significantly deformed ( Fig. 12B ). Pupation in the mine. Trophic specialization. Oligophagous on Betulaceae : Alnus maximowiczii , Betula ermanii ( Kumata 1963 ; Ermolaev 1987 ), Betula platyphylla ( new record ). Distribution.
