Abstract

This article presents the first records of five species of moths and butterflies from Kunashir Island. We report on the first records of Lampides boeticus (Linnaeus, 1767), Macroglossum saga Butler, 1878, Ampelophaga rubiginosa Bremer & Grey, 1853, Catocala electa (Vieweg, 1790), and C. praegnax Walker, 1858 from Kunashir Island. Additionally, we provide commentary on the distribution of Bombyx mandarina (Moore, 1872), Caligula japonica Moore, 1862, C. jonasii (Butler, 1877), Macroglossum stellatarum (Linnaeus, 1758), M. pyrrhosticta Butler, 1875, Agrius convolvuli (Linnaeus, 1758), Catocala dula Bremer, 1861, C. lara Bremer, 1861, C. dissimilis Bremer, 1861, C. deuteronympha Staudinger, 1861, C. nupta (Linnaeus, 1767), C. fraxini (Linnaeus, 1758), Lymantria mathura (Moore, 1866), and Orgyia thyellina (Butler, 1881).

Introduction

The Lepidoptera fauna of Kunashir Island was poorly understood for a long time. However, a species list of many families was significantly updated due to research carried out since 2017 (Rybalkin and Yakovlev 2017; Rybalkin 2020a, b; Rybalkin et al. 2018, 2019, 2022; Spitsyna and Spitsyn 2023; Koshkin et al. 2023; Dubatolov et al. 2023). This article is a continuation of the study of the Lepidoptera fauna of Kunashir Island and is focused on the autumn aspect of the fauna.

Materials and methods

Moth and butterfly specimens were collected using an ultraviolet lamp and entomological net. The images of the specimens were taken using an Olympus OM-D E-M10 Mark II camera with an Olympus M.ZUIKO 30mm f/3.5 ED Macro lens. The studied specimens are deposited at the Russian Museum of Biodiversity Hotspots (RMBH), N. Laverov Federal Center for Integrated Arctic Research of the Ural Branch of the Russian Academy of Sciences, Arkhangelsk, Russia.
