Garaeus specularis Moore, 1868

Material. Danilovskii Cordon, at light, 18.09.2022 — 1♂; Andreevskii Cordon, at light, 25– 26.09.2022 — 1♀.

Distribution. Russia (S RFE: S Kurils — Kunashir); China (SW, Central and E, Taiwan),? Korea, Japan (Hokkaido, Honshu, Shikoku and Kyushu), NE and N India, Nepal.

Remarks. The species was first reported from Kunashir by Rybalkin (2020) at the first half of September in a large number of individuals. In Japan it develops in two generations, moths are common everywhere and can be seen from July to October; overwinters as eggs ( Sato 2011). On Kurils, evidently, it produces only one generation, as at summer time it has never been met. On Kunashir, in Japan and Korea the subspecies Garaeus specularis mactans (Butler, 1878) (= fenestratus Butler, 1881) is distributed, which, however, weakly differs from nominative form from India ( Sato 2011). Presence of this species in Korea needs to be confirmed, as there is no other information ever since Prout (1912) first reported it without collection site data ( Kim et al. 2016). Larvae are polyphagous, in Japan they feed on various arboreous leaved plants ( Sato 2011).
