An ecological study of aquatic insects was conducted at Chojong stream from September 1992 to August 1993. The taxa of aquatic insects of the study period composed of 152 species, 94 genera, 53 families, 9 orders. Dominant taxa were Ephemeroptera(53%), Trichoptera(34%) and Diptera(10%). Functional feeding groups dominated scrapers and collectors at upper stream(site 1, 2 and 3), filterers and collectors abundanced at middle stream(site 4, 5, 6 and 7). Tolerance groups dominated at middle stream. Monthly diversity indicies were relatively inconsistant at the sites 4 and 5 compared with other sites. Study sites were clustered most similar sites between 4, 5 and 7 by UPGMA. Chojong stream was characterized by water quality in the phase of β-mesosaprobic and α-mesosaprobic.

본 연구는 국내에 서식하는 파파리반딧불이의 암컷과 수컷의 발광양상을 분석하고자 실시하였으며 발광양상은 암컷과 수컷의 정지발광과 구애발광을 구분하여 조사하였고 각각의 발광지속시간과 발광주기를 구분하여 측정하였다. 수컷의 발광지속시간은 정지발광(0.12초)보다 구애발광(0.17초)에서 1.4배 증가하였으며 암컷의 발광지속시간은 정지발광(0.15초)보다 구애발광(0.19초)에서 1.5배 증가하였다. 발광 주기는 수컷에서 정지발광(1.26초)보다 구애발광(1.12초)에서 0.88배 감소하였고, 암컷에서 정지발광(2.99초)보다 구애발광(1.06초)에서 0.35배 감소하였다. 발광양상에서 발광주파수는 수컷의 정지발광에서 0.8Hz, 수컷 구애발광 0.9 Hz, 암컷의 정지발광 0.3 Hz, 암컷의 구애발광은 0.9 Hz로 각각 나타났다. 파파리반딧불이의 발광파장영역은 400nm에서 700 nm에 이르는 모든 영역에서 확인되었으며 가장 높은 첨두치는 600 nm에 있고 500에서 600 nm사이의 파장대가 가장 두드러지게 나타났다. Luminescent patterns of the firefly Hotaria papariensis were classified into routine flashing and courtship flashing, and they were analyzed into duration and period. Flash period of male was changed from 1.26 sec (routine flashing) to 1.12 sec (courtship flashing) and the female's was changed from 2.99 sec to 1.06 sec in this species. Duration time of male increased approximately 1.4-fold from 0.12 sec (routine flashing) to 0.17 sec (courtship flashing) and period of male decreased 0.88-fold from 1.26 sec (routine flashing) to 1.12 sec (courtship flashing). Duration of female increased about 1.5-fold from 0.15. sec (routine flashing) to 0.19 sec (courtship flashing) and period of female decreased almost 0.35 from 2.99 sec (routine flashing) to 1.06 sec (courtship flashing). Hertz frequencies of them were 0.8 (routine flashing of male), 0.9 (courtship flashing of male), 0.3 (routine flashing of female) and 0.9 (courtship flashing of female), respectively. The spectral emission of H. papariensis was detected at 400 nm to 700 nm, and the highest peak wave length of this species was approximately 600 nm, but some 500 to 600 nm wave lengths were present.

한국산 Hotaria속 반딧불이 2종의 고도별 출현 및 분포양상을 알기 위해 1999년 5월부터 7월까지 18개 지역을 선정하여 조사하였다. 전체 채집 개체수는 1,096 개체였으며 이중 파파리반딧불이(H. papariensis)는 584개체, 운문산반딧불이(H unmunsana)는 512 개체였다. 이를 토대로 고도별 출현성기를 알아본 결과 200 m 이하 지역에서는 6월 초순에서 중순, 200∼400m 지역에서는 6월 중순에서 말경, 400∼600m 지역에서는 6월말 경부터 7월 초순, 600∼800 m 지역에서는 7월 초순부터 중순에 각각 최고 성기를 나타내었다. 두 종은 제주도를 제외한 전 조사지역에서 공서하고 있었으며 H papariensis는 북쪽지역에 우세하게 분포하였고, H unmunsana는 남쪽지역에 우세하게 분포하는 양상을 나타내었다. We have collected two species of firefly, Hotaria papariensis and Hotaria unmunsana to investigate their patterns of appearances and distributions from May to July in 1999 at 18 localities in Korea. A total of 1,096 individuals of these two species were collected: H. papariensis 584 and H unmunsana 512. The highest appearance level of adult firefly was different from each altitude. They appeared from the beginning of June to the end of June at 200 m sea level, the middle of June to the end of June at 200∼400 m, the end of June to the beginning of July at 400∼600 m and the beginning of July to the middle of July at 600∼800 m, respectively, All regions of these two species were cohabit, but Cheju-do region is the exceptional case. H papariensis was dominant at the northern parts and H unmunsana was the southern parts of Korean peninsula.
