Phyllonorycter populifoliella ( Treitschke, 1833)

( Fig. 7C )

Material examined. Russia: KK, Komsomolsk-na-Amure , city plantation, 50.58N, 137.04E, 32 m alt., Populus sp., 13.VII.2010, 1 pupa, NK88 , MK 403730 ; AO, Blagoveshchensk , Friendship park, 50.29N, 127.53E, 137 m alt., P. balsamifera , 27. VI.2016, 1 pupa, NK561 , MK 403712 , 1 male (reared from mine), NK561-1 / [NK561-1-male] ( Fig. 7C ), deposited in INRA.

Leaf mine. The mine is a blotch similar to that of Ph. pastorella , but with a shorter preceding epidermal tunnel that can be seen in the later stage when the blotch part of the mine spreads on the surface. The mine is usually on the lower side of the leaf between secondary veins or nearby leaf margin. Often several mines per leaf. In dense populations, upper side mines can be found. Pupation in the mine.

Trophic specialization. Monophagous on Populus : P. nigra , P. suaveolens , P. laurifolia , P. balsamifera , P. deltoids , P. simonii , and the hybrids— Populus x canadensis, Populus x canescens ( Salicaceae ) ( Ellis 2018; De Prins & De Prins 2018). Records of P. alba and P. tremula may need confirmation as Ph. populifoliella mines can be mixed up with those of several other Phyllonorycter species developing on these plants: Ph. apparella , Ph. comparella , Ph. connexella , Ph. pastorella ( Ellis 2018) .

Distribution. Russia: RFE—KK (Baryshnikova 2016), AO (new record), Siberia, European part ( Baryshnikova 2008); Central Asia, Europe ( De Prins & De Prins 2018).
