The two East Asian subtropical–tropical noctuoid moths, Nyctemera adversata (Schaller, 1788) (Erebidae: Arctiinae) and Dictyestra dissectus (Walker, 1865) (Noctuidae: Noctuinae), are newly recorded in the Russian Far East on an extreme long distance to the north from their known localities in the neighboring countries. They were collected on the small Rikord Island in the Peter the Great Gulf after the period of strong southern wind associated with Typhoon Chaba. Data on the general distribution and bionomics of these species are given. This founding, along with other similar discoveries, is consistent with the current trend of global climate warming and indicates a northward expansion of the ranges of southern species in the Sea of Japan/East Sea region. Large migratory moths effectively use powerful air currents to move long distances, including over the sea, while small coastal islands can be used by them as intermediate sites and/or for possible establishing of invasive populations.

Статья посвящена исследованию малоизвестной фауны пядениц (Lepidoptera: Geometridae) среднего сектора восточного Сихотэ-Алиня, российского Дальнего Востока, центральной частью которого является Ботчинский заповедник. В первой части рассмотрены история исследований, локализация и описание пунктов сборов, методы сбора материалов и подходы к типизации ареалов Geometridae, а также приводятся материалы по подсемействам Archiearinae, Ennominae, Desmobathrinae и Geometrinae. В этих подсемействах выявлено 86 видов пядениц, из которых 82 вида найдены на территории Ботчинского заповедника и его охранной зоны. Среди них Ourapteryx maculicaudaria (Motschulsky, 1866) и Charissa remmi Viidalepp, 1988 — новые для Хабаровского края, а 69 видов первые отмечены на исследуемой территории.

An annotated list of 12 species of geometrid moths of the subfamily Larentiinae (Lepidoptera: Geometridae) found for the first time on the territory of Amurskaya Oblast, the Russian Far East, is given. There are: Brabira artemidora (Oberthür, 1884), Acasis bellaria (Leech, 1891), Trichopteryx polycommata ([Denis et Schiffermüller], 1775), Idiotephria debilitata (Leech, 1891), Idiotephria evanescens (Staudinger, 1897), Thera variata ([Denis & Schiffermüller], 1775), Ecliptopera umbrosaria (Motschulsky, 1861), Triphosa dubitata (Linnaeus, 1758), Triphosa sericata (Butler, 1879), Operophtera relegata Prout, 1908, Hydrelia parvulata (Staudinger, 1897), and Venusia semistrigata (Christoph, 1881). From them, for 9 East Asian species these finds strongly expand to north-west their previously known areas.
