ダイミョウセセリ Daimio tethys (Menetries, 1857) は，中国・朝鮮半島・台湾・ロシア・日本にかけて分布し，日本の本州・四国・九州では普通種である．北海道では道南の渡島半島のごく一部に分布が限られる稀種とされてきたが，2019年を最後に記録がなく地域絶滅したと考えられていた．著者は2024年に北海道檜山郡江差町で本種のメス成虫を採集したので，北海道においてダイミョウセセリがいまだ絶滅していないことを示唆する記録として報告する．

In Japan, adults of Hedya gratiana Kawabe, 1974 (Lepidoptera, Tortricidae) are found to exhibit two different wing pattern forms that are unrelated to the sexes. The adults and genitalia are illustrated, and the partial mitochondrial COI sequences are provided.

Head capsule widths of Neozephyrus japonicus japonicus larvae collected in Ibaraki Prefecture, Central Japan were measured. The butterfly passes through four larval instar stages before pupation. The mean head capsule widths of the first, second, third and fourth (final) instar larvae were 0.331, 0.585, 1.059, and 1.909 mm, respectively.

Plebejus argus seoki Shirôzu & Sibatani, 1943 (Lepidoptera: Lycaenidae) was described from Jeju Island, Korea, based on specimens collected by Du-Myung Seok. Shirôzu and Sibatani (1943) incorrectly indicated the holotype of this subspecies in their original description. To avoid taxonomic confusion, we illustrate the true holotype deposited at Kyushu University for the first time.

Nemophora seraphias (Meyrick, 1907) (Adelidae, Adelinae), originally described from Assam, India, is reported from Myanmar for the first time. Specimens from Myanmar are distinct, having fuscous forewing markings, and therefore they are described as Nemophora seraphias fuscata Hirowatari & Jinbo, subsp. nov. This is the first report of this species in nearly 100 years. The nearest relatives of N. seraphias are discussed based on DNA barcode sequences.

アオタテハモドキJunonia orithya (Linnaeus, 1758) はアフリカからアジア，オーストラリアにかけての熱帯地域に広く分布する．日本では，沖縄島より南部では確実に土着しており，それ以北では定着と消滅を繰り返している．高知県では複数の偶発的な記録が知られている．本報では，2023・2024年の室戸市周辺における本種の採集・観察事例と2025年の南国市における5頭の採集記録を新たに報告する．

We recorded the hemlock moth, Agonopterix alstromeriana (Clerck, 1759) from Japan for the first time. We determined based on both morphology and DNA analysis. The haplotype from Hokkaido, Japan we analyzed was completely consistent with the most common haplotype known from the world. The seasonal occurrence of this species was investigated by light trapping on the Sapporo Campus of Hokkaido University over six years. The results of this study revealed that adults live for almost one year, until just before the emergence of new adults. The species is not considered to be highly migratory, and its introduction into Japan is likely to have been artificially induced during its long adult life span, possibly by being mixed in with some kind of material. Although this species is highly effective as a biological control agent against hemlock in a small community, it is not promising as a means of large-scale control.
