Idaea pallidata (Denis et Schiffermüller)

( Fig. 56 , 68a, 68b )

Idaea pallidata : Beljaev & Mironov 2019: 277 (Sakhalin).

Material examined. 2 ♂, Tymovskoe, 8.VI.2003.

Distribution. Russia (RFE: central Sakhalin, central Khabarovskii Krai, Amurskaya Oblast; S Yakutia, S and W Siberia, Urals, European Part, N Caucasus), NE China (Heilongjiang), Mongolia, Kazakhstan, N Kyrgyzstan, Transcaucasia, Turkey, Europe.

Remarks. The finding of I. pallidata in Sakhalin significantly expands its distribution range to the east. This meadow species, strictly boreal in East Palearctic, was found in the central Sakhalin in a zone of the spruce-fir forests dominance. In the Europe the larvae feed on the wilted leaves of various dicotyledonous herbs and low shrubs— Taraxacum , Hieracium , Achillea ( Asteraceae ), Vaccinium ( Ericaceae ), Valeriana ( Caprifoliaceae ), and Filipendula ( Rosaceae ).
