Caloptilia acericola Kumata, 1966

( Fig. 10D )

Material examined. Russia: PK, Gornotaezhnoe , forest around MTS, 43.70N, 132.15E, 264 m alt., Acer pseudosieboldianum , 22.VII.2016, 1 larva, NK539 , MK 403697 , deposited in INRA.

Leaf mine. The mine is a small, slightly contorted brownish blotch along main vein or between secondary veins ( Fig. 10D ), usually on the lower side of the leaf, with or without short epidermal tunnel. Black grains of frass are accumulated in the blotch mine along its margin. After vacating the mine, the larva creates up to three shelters (usually on the same leaf): at the beginning, it feeds in the folded downwards leaf margin, then moves to another margin and rolls it downwards starting from leaf tip, soon after it rolls downwards a bigger part of the leaf and feeds in this construction ( Fig. 10D ). Pupation in a whitish shining cocoon attached to the leaf margin.

Trophic specialization. Monophagous on Acer : A. japonicum , A. palmatum , A. pictum , A. pseudosieboldianum (Sapindaceae) (Baryshnikova 2016; De Prins & De Prins 2018).

Distribution. Russia: RFE—PK ( Ermolaev 1988; Baryshnikova 2008), Japan ( Kumata 1966).
