  • The Dryopidae (Coleoptera) is composed of approximately 300 species worldwide belonging to 33 genera; however, members of the family have not been recorded in Korea. We collected and recorded adult specimens of Elmomorphus brevicornis Sharp (=E. brevicornis brevicornis Sharp) on piles of submerged twigs and branches of a decayed tree (Prunus sp.) from a mountain stream in southwestern Korea with a comparison of the type specimens of E. brevicornis amamiensis Nomura from Japan. Both of the subspecies are raised to the species level herein. Redescription, photographs, line drawings of diagnostic characteristics, distribution map, habitat, and taxonomic notes for Elmomorphus brevicornis are provided.

  • In this paper, we propose a better solution for swimming plans of an articulated underwater robot, Crabster, with a view point of biomimetics. As a biomimetic model of underwater organisms, we chose diving beetles structurally similar to Crabster. Various swimming locomotion of the diving beetle has been observed and sorted by robotics technology through experiments with a high-speed camera and image processing software Image J. Subsequently, coordinated patterns of rhythmic movements of the diving beetle are reproduced by simple control parameters in a parameter space which make it easy to control trajectories and velocities of legs. Furthermore, a simulation was implemented with an approximated model to predict the motion of the robot under development based on the classified forward and turning locomotion. Consequently, we confirmed the applicability of parameterized leg locomotion to the articulated underwater robot through the simulated results by the approximated model.

  • Diet composition of amphibians usually reflects the distribution of potential prey within habitats, as well as their diet preference. We identified the diet items of Japanese tree frog (Hyla japonica) using a stomach flushing method in a rice paddy for the establishment of bio-monitoring systems of landscape changes. During the reproductive period, 71% of calling males had empty stomachs. All prey items in the stomachs belonged to the phylum Arthropoda, from eight orders of Insecta and one order of Arachnida. Among insect prey, the most common items in the stomachs were adults of beetles, flies and bugs, and larvae of butterflies and moths. There was a significant positive correlation between the body mass of Japanese tree frogs and the volume of prey items. Our results can provide a basic framework to guide the monitoring systems using prey identification of Japanese tree frogs.

  • At the Changnyeung natural bod, the flood in the freshwater wetland and the adaptation of the insect at this area were investigated by the species diversity index and the cluster analysis. Most dominant species was Diplonychus esakii collected at the site of the water edge and its dominance index was 0.797. This area had lower species diversity indices with the value of 0.340 to 1.712 than that of the grassland and water stream. The number of the species in this area was not rich. Some ground beetles inhabited at the flooded or wet area were important species for the pair group between the sites by the cluster analysis. The composition of the insect species at this natural wetland affected by the irregular flood was very simple and specific.

  • This paper deals with Korean Staphylinids fauna investigated in Korea by G. Lafer during 1994, 1995 and 1998. 38 species of rove beetles were recognized and among them, four species (Atheta weisei, Bolitobius setiger, Lesteva plagiata, and Sepedophilus germanus) are reported herein from Korea for the first time.

  • The taxonomic study of the genus Myzia Mulsant, 1846 in Korea is presented. The genus Myzia contains five species worldwide and two species currently recognized in Palaearctic region. Until now, only M. oblongoguttata (Linnaeus, 1758) has been known in Korea, but we found M. gebleri (Crotch, 1874) for the first time in Korea. We redescribed these two Korean species of the genus Myzia with photographs of the habitus and detailed illustrations of their aedeagus and other appendages. A taxonomic key to the species of Korean Myzia beetles are also provided.

  • Difference of the inset diversity and community structures between the bog Hwaeom-neup and its surrounding forest of Mt. Wonhyo-san located at Yangsan were investigated. Overall 15 orders, 87 families, 204 genera and 233 species were identified. Hydrophilic Harpalidae species were observed in small number at the bog, while the insect species representing hardwood forest were also collected at the bog. Species diversity was relatively higher at the forest (H'=4.80) than at the bog (H'=4.10). The dominant species was Diplous depressus (Gebler) both at bog as well as at forest. Ground-walking Coleoptera as Carabus sternbergi stembergi Roeschke, Damaster jankowskii jankowskii (Oberthur) and D. depressus was spread from forest into bog. Longhorn beetles Leptura arcuata Panzer and Chlorophorus diadema (Motschulsky) being characteristic species of shrub forest were also observed spreading into bog. It was consequently suggested that the bog was in part progressed into dry succession and its boundary was not clearly defined with forest at least upon the structure of insect commnunity.
