Abstract

The purpose of this study is to identify insects inhabiting Mulyeongari-Oreum wetland and to provide basic information for conservation of wetlands. As a result, a total 229 species, 73 families, 9 orders of insects were collected: 136 species, 39 families, 6 orders from Mulyeongari-Oreum Wetland and 121 species, 52 families, 9 orders from Mt. Sooryeong. Of the 229 species of insects investigated, Copris tripartitus Waterhouse, an endangered species of wildlife fauna in Korea, was found with many individuals. Also, Lychnuris rufa(Olivier), having a narrow habitat near unpolluted water and mountains, was also recorded with 3 individuals and then should be considered as a protected species in Wetlands. To identify the community structure of moth on Mulyeongari-Oreum wetland, a light trap was examined and a total 76 species of moths were collected. Total dominant species was Hydrillodes morosa(Butler) with index of 0.12 and the species diversity on the moth community from survey area was the highest in July with index of 3.42.

본 논문은 물영아리오름 습지에 서식하는 곤충류를 파악하여 습지 보전에 대한 기초적인 정보를 제공하고자 실시되었다. 조사결과 총 9목 73과 229종이 조사되었으며, 물영아리오름 습지는 6목 39과 136종, 수령산은 9목 52과 121종이 조사되었다. 조사된 229종의 곤충류 중 멸종위기종인 애기뿔소똥구리가 포함되었다. 또한 오염되지 않은 습한 산 주위에서 주로 서식하는 늦반딧불이가 3개체 조사되었으며 이는 청정지역임을 나타내는 대표적인 종으로 습지에서 보호되어야 할 가치가 있는 것으로 판단된다. 또한 물영아리오름 습지의 나방류 확인을 위해 야간 유인등 조사를 실시하였으며 조사 결과 총 76종이 조사되었다. 넓은띠담흑수염나방이 0.12의 우점도 지수로 전체 우점종으로 조사되었으며, 종다양도는 7월 조사에서 3.42로 가장 높게 나타났다.
