Eupithecia scribai Prout 1938

Eupithecia scribai Prout, 1938 (Fig. 3 J) Material. Andreevskii Cordon, 15–16, 19–20, 26– 27.10.2023 – 1♂, 2♀; ibid.: 1 – 2.11.2023 – 1♀, 3– 4.11.2023 – 2♀, 6– 7.11.2023 – 1♂, 1♀. Distribution. Russia (S RFE: Khabarovsk Kr., Primorsky Kr., Sakhalin, S Kurils – Iturup, Kunashir, Shikotan); Japan (Hokkaido, Honshu – north of Chubu region), South Korea. Remarks. Previously, E. scribai was observed on Kunashir only in July and August (Vasilenko 1992; Eupithecia scribai … 2024). In the Chubu region of Honshu, the species occurs in the mountainous areas above 1500 m a. s. l. and its moths appear in July and August (Nakajima, Yazaki 2011). The moths collected on Kunashir in late October and early November are likely from an accidentally hatched wintering generation. V. G. Mironov of the Zoological Institute (Saint Petersburg, Russia) suggests that these specimens represent an anomalous ‘deadlock’ generation (personal communication). The host plant of the larvae remains unknown.
