Remarks. In Japan moths appear from May to November and occur 2–3 times a year, larvae are recorded on 18 species of plants form Polygonaceae , Rosaceae , Ericaceae and Asteraceae ( Nakajima, Yazaki 2011) . Howev- er, the taxonomy of moths, in Japan currently associated with D. citrata , needs revision, as a possible mix of several species ( Beljaev 2016). In Europe, the species develops in one long generation, moths usually occur from later June to mid-September ( Hausmann, Viidalepp 2012), which is generally consistent with the tier occulting on RFE. Larvae in Europe are polyphagous on low trees, shrubs and prostrate shrubs, prefer Ericaceae ( Hausmann, Viidalepp 2012) .
