* Orthonama obstipata (Fabricius, 1794)

Material. Danilovskii Cordon, 11– 12.10.2022 — 1♂.

Distribution. Russia (European part, N Caucasus, Urals, S Siberia, S RFE: Amurskaya Obl., Khabarovskii Kr., Primorskii Kr., Sakhalin, S Kurils — Kunashir); almost cosmopolitan, except most northern and most southern territories, and Australia.

Remarks. A new species for the Kuril Islands, but possibly migrant, as in Europe north of subtropics ( Hausmann, Viidalepp 2012). In Japan it occurs through all islands, is common, and moths appear from the end of March to the beginning of November ( Nakajima, Yazaki 2011). Larvae are polyphagous on herbs, shrubs and trees.
