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.

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. Moonlander Moth Trap과 버킷식 유아등 트랩을 이용하여 나방류를 채집하 였고, 본 연구에서 확보된 연구재료 이외에도 과거에 소나무림에서 채집된 한남대학교 동물분류학연구실 소장 나방류 표본을 포함하였다. 조사 결과, 총 32과 407속 589종의 나방류 곤충이 조사되었으며, 이 중 소나무를 섭식 하는 등 소나무류와 직접적으로 관련되는 나방류는 총 10과 26속 30종으로 파악되었다.

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.
