  • A total of 27 species of Carabidae from Korea is listed. Of these, 9 species, Badister ussuriensis, Bembidion aurefuscum, Bradycellus anchomenoides, Desera geniculata, Diplocheila elongata, Harpalus quadripunctatus, Odacantha aegrote, Trichotichnus longitarsis, and Trichotichnus nishioi are reported for the first time from Korea.

  • Aerodynamic characteristics of Coleoptera species of Epilachna quadricollis and Allomyrina dichotoma are experimentally and numerically investigated. Using digital high speed camera and smoke wire technique, we visualized the continuous wing kinematics and the flight motion of free-flying coleoptera. The experimental visualization shows that the elytra flapped concurrently with the main wing both in the downstroke and upstroke motions. The wing motion of Epilachna quadricollis was captured and analyzed frame by frame to identify the kinematics of the wings and to implement it in the movement of a model wing (thin plate) in the simulation. The two-dimensional simulation of Epilachna quadricollis hovering flight was performed by assuming the wing cross section shape as a thin plate, even though most of insect's wings are made of curved corrugated membrane. The effect of Reynolds number are investigated by the simulation. Meanwhile, in order to investigate the role and effect of elytra, the flow visualization of Allomyrina dichotoma was carried on using smoke wire visualization technique. Here, we confirmed that the vortex generated by elytra due to its movement is strongly influence the vortex dynamic generated by hind wings.

  • The taxonomic revision was made on the tribe Harpalini (Coleoptera: Carabidae) in Korea. The Korean species are arranged after Kryzhanovskij et al. (1995) system with minor emendation. This present list is an attempt to bring together the available literature and collection-based information on fauna or taxa recorded from Korea (including some collections from the northern part of the Korean Peninsula, now North Korea). Materials examined for each species, an annotative checklist of Korean Carabidae, and the practical key to tribes and genera are provided. As a result, a total 86 species (and subspecies) belonging to 13 genera are recognized from the Korean Peninsula, of which one species (Harpalus egorovi) is new to South Korea. Distribution of two species, Harpalus tardus and H. tibeticus hsifanicus, are very doubtful in the Korean Peninsula. Besides, numerous new distribution records are given as based on materials deposited in various Universities and private collections.

  • A flow visualization is conducted to investigate a flight characteristics of a Coleoptera and an effect of flapping elytra was considered in this study. Also the movements of outer wing(elytra) and inner wing is analyzed using High Speed Camera. As a result of this experiment, in case of flapping insect, three mechanisms to generate lift is confirmed. A small movement of outer wing(elytra) is confirmed and the effect of outer wing(elytra) is estimated.
