We analyzed comparatively the ground beetle communities of 1993 and 2023, with 30 year interval, in broadleaf and coniferous stands of the Gwangneung forest, a biosphere reserve in South Korea. 2,906 individuals (53 species, 38 genera, and 15 families) were collected from broadleaf stands and 1,782 individuals (36 species, 32 genera, and 14 families) from coniferous stands in 1993. The dominant species was Synuchus cycloderus in both stands. In 2023, 1,682 individuals (110 species, 78 genera, 21 families) were collected from broadleaf stands and 990 individuals (92 species, 67 genera, 22 families) from coniferous stands. In 2023, the dominant species were Eucarabus (Parhomopterus) sternbergi sternbergi in broadleaf stands and Coptolabrus jankowskii jankowskii in coniferous stands. Species richness (R'), species evenness (E'), species diversity (H'), and dominance (DI) were all higher than in broadleaf (R'=15.472, E'=0.336, H'=1.601, and DI=0.371) and coniferous (R'=13.756, E'=0.369, H'=1.324, and DI=0.326) forests in 2023.

Vespidae are social insects and crucial predators that prey upon various insects. In particular, Vespa velutina nigrithorax, as a representative predator of honey bees, inflicts huge economic damage on apiary. Therefore, it is essential to investigate the national distribution of vespid wasps. In this study, collection was made, in 73 study sites, using hornetluring traps and malaise traps in Gangwon-do, Gyeonggi-do, Gyeongsang-do, Chungcheong-do, and Jeju-do from 2019 to 2022. As a result, a total of 24,974 individuals of 24 species, 5 genera, and 2 subfamilies were collected, with the largest number of species collected in Gangwon-do (22 species, 5 genera, and 2 subfamilies). Also, Vespa simillima simillima (38.2%), Vespa crabro flavofasciata (25.1%), Vespa crabro flavofasciata (23.8%), Vespa velutina nigrithorax (27.5%), and Vespa simillima xanthoptera (54.6%) are the dominant species in each province, respectively. Species richness (R') and species evenness (E') were highest in Gyeonggi-do (R'=2.712, E'=0.978), and species diversity (H') was highest in Gyeongsang-do (H'=2.981). Dominance was highest in Jeju-do (DI=0.719). Herein, we provide basic data needed in development of vespid damage management systems using regional sampling data and forest geospatial information in the study area.

본 연구는 우리나라 소나무림 내 나방류 곤충의 분포상을 파악하기 위해 수행되었다. 우리나라 산림면적은 634만 ha로 국토의 약 63.2%를 차지하고 있으며, 그중 소나무림의 면적은 총 156만 ha로 산림면적의 25.9%를 차지하고 있는 중요 수종이라 할 수 있다. 우리나라 주요 소나무림의 나방류 조사를 위해 지형특성별로 동해안 산림, 내륙지대 및 해안지대로 먼저 구분하였고, 이들 지역 중 소나무림 19개소를 조사대상지로 선정하여 2021년 4월부터 2022년 9월까지 수행되었다.

Machilus thunbergii (Laurales: Lauraceae, 후박나무) is planted as a street tree in Jeollanamdo and Jeju Island. Orthaga olivacea (Lepidoprate: Pyralidae, 제주집명나방) is known as a major pest of M. thunbergii. For managing O. olivacea by eco-friendly control method, the mating disruption would be expected. The sex pheromone of O. olivacea was identified as a mixture of (Z)-11-hexadecenyl acetate (Z11-16Ac), (Z)-11-hexadecenal (Z11-16Ald), and (Z)-11-hexadecenol (Z11-16OH) at a ratio of 100: 0.1:0.1 by Chinese research group. Before applying mating disruption, confirmation of its attraction in Korea was essential. The pheromone traps composed of Z11-16Ac alone and the blend of three components (100:0.1:0.1) were installed in Haenam, Jeollanamdo in 2021, and Jeju and Seogwipo, Jeju in 2022. In field attraction test, no O. olivacea was attracted to any trap. However, Mamesastra brassicae (Lepidoptera: Noctuidae), which was not intended, was caught in both years in the trap. Total of 19 in Haenam between September 23 and 30, total of 11 in Jeju between September 30 and October 28, and total of 108 in Seogwipo between September 15 and November 11 were caught to the trap lured with Z11-16Ac. While in the trap lured with the blend, total 1 and 6 were captured in Haenam and Seogwipo, respectively.

Until now, in case of Palaearctic region, only one species, Nesendaeus monochrous in this genus was recorded from China. but the biology and life cycle are not clearly known, yet. This species collected from the bud of Glochidion chodoense in Korea for the first time and closely related to Heterochyromera imerodeus Kojima & Morimoto which was recorded only in Japan,. But Nesendaeus monochrous is easily distinguishable from H. imerodeus by the relatively longer elytra with bisinuately round apices. Heterochyromera imerodeus Kojima & Morimoto can be found from Eurya emarginata and Glochidion obovatum in Japan. So, this two species are closely related each other and need more taxonomic study about the generic synonymy or changing the generic position.

Milichiidae Schiner, 1862 is a small family of Diptera, with 19 genera and 360 described species worldwide. In Korea, only two species in a single genus, Aldrichiomyza Hendel, 1914, have been recorded. Milichiid species, small-sized acalyptrate flies, are generally associated with decaying plants and animals. In particular, Desmometopa Loew, 1866 in the family has a commensalistic habit, more precisely the phoretic relationship, that has been observed with predacious insects and spiders, in which adults feed on the juices of the prey. In this study, we recognized Desmometopa microps Lamb, 1914 for the first time in the Korean Peninsula. This is also the first record of the genus from the country. Herein, we provide diagnosis of D. microps based on the Korean specimens with images.

Curtonotidae, known as the quasimodo flies, in Diptera currently includes about 100 described species in five genera (Axinota Wulp, 1886; Curtonotum Macquart, 1844; Cyrtona Séguy, 1938; Depressonotum Grimaldi & Kirk-Spriggs, 2012; Tigrisomyia Kirk-Spriggs, 2010) worldwide. Curtonotid species have great potential as case studies for biological diversity, evolution, and zoogeography based on wide distribution and sufficient diversity. In the present study, Curtonotum maritimum Ozerov, 2007 is newly added to Korean insect fauna. This is also the first record of Curtonotidae from the country. We here provide morphological diagnosis and images including genitalic structures for accurate identification.

Necrophila (Calosilpha) brunnicollis brunnicollis (Kraatz, 1877) is a common necrophagous beetle in the Palaearctic region. The species is often encountered on the corpses of large vertebrates, such as human and pig, and is well recognized as a potentially group of beetles in forensic entomology. All of the developmental stages can be found in the corpse and under the soil near a corpse, which can be used to reconstruct the site, such as estimating PMI(Postmortem interval). However, its larval instar stages were never thoroughly described for identification. In this study, we redescribe the morphological characters of all larval stages of N. brunnicollis for quantitative and qualitative morphological information. In addition, we provide the images of larvae and an indentrifiaction key to larval instars.

The genus Silpha Linnaeus, 1758 in Silphinae includes 33 species worldwide. This group is flightless and known to feed on invertebrate carcasses from the ground surface. In South Korea, 3 species have been recorded, and S. koreana Cho& Kwon, 1999 is an endemic species, distributed only Mt. Taebaek and Mt. Mindung. Up to date the immature stages of the species has never been studied although the species has significant value as an endemic species. The present study is the very first one ever conducted describing the larval morphological characters of S. koreana along with images of larval stages. Furthermore, we report observations on developmental lengths for each stages of the species.

The family Crambidae, so called as Grass moths, have been known as a difficult group in identification due to their similar wing patterns among the allied species. Some species are well known as pests to the agricultural and ornamental plants of economic importance. Therefore, this study was carried out to provide the DNA barcode and related information for distinguishing the complex species among Crambidae. In this study, we extracted and analyzed the DNA barcodes from 185 specimens of 76 species in the family Crambidae. Based on the result, one species of the genus Schoenobius, Pagyda, Neoanalthes, Palpita, Ecpyrrhorrhoe and Paratalanta area reported for the first time from Korea.
