광릉 숲의 곤충상 조사는 1932년으로 거슬러 올라간다. 광릉 숲의 경로조사법에 의한 나비상 모니터링 연구는 1998년부터 2023년까지 지속되었다. 26년 동안 총 223회 조사를 실시한 결과 118종, 20,181개체가 확인되었다. 봄철 출현하는 나비중 8종(노랑나비, 대만흰나비, 먹부전나비, 멧팔랑나비, 쇳빛부전나비, 애호랑나비, 큰줄흰나 비, 흰줄표범나비)은 첫 출현일이 빨라지는 경향을 보였으며, 평균 5.2일 빨라졌다. 조사된 나비중에서 큰줄흰나 비, 뿔나비, 남방부전나비 순서로 많은 개체수가 확인되었으며, 연 출현 빈도는 큰줄흰나비가 26회로 가장 많았다. 확인된 나비의 분포, 서식지, 식성에 따라 분류한 결과 분포는 북방계 27%, 남방계 14%이며, 서식지는 산림 경계 36%, 산림 내부 33%, 초지 30% 그리고 식성은 다식성 8%, 단식성 42%, 협식성 51%로 이루어진 것이 확인되었다. 또한, 기후변화 따른 나비류 생활주기 변화 여부를 검토하여 지구온난화 지표 자료로 활용할 계획이다.

Hindwings of many lycaenid butterflies have a unique tail-like wing structure referred to as a false head, which actually mimics the antennae. False heads increase butterfly survival by directing predatory attacks towards the false heads thereby enhancing the chance of escape. In this study, using discrete character evolution models of European and American butterflies, we examined the co-evolutionary patterns between false head structures and two associated traits: a highly contrasting color patch neighboring the false head, and hindwing rubbing behaviors. The former is considered a eye-mimicking structure that enhances the effectiveness of false head, and latter generates the movement of false heads which likely increases the success of false head deception. Our findings demonstrate that false heads are ancestral states for both European and American lycaenids. Both contrasting colors and hindwing rubbing behaviors follow correlated evolution models, suggesting that these traits co-evolved in lycanid butterflies. However, specific evolutionray patterns differed between the two continents.

이 연구에서 지리산의 낮은 고도에서부터 높은 고도까 지 나비의 종다양성, 고도에 따른 생태적 특성, 우점종의 고도 분포에 대해 알아보았다. 나비는 총 5과 58종 769개체의 나비를 확인하였다. 낮은 고도와 높은 고도에서 종다양성은 높게 나타나고 있었다. 군집분석을 통해 3개 (낮은 고도, 중간 고도, 높은 고도)로 구분하였으며, 낮은 고도에 비해 높은 고도에서는 서식지 범위가 좁은 종의 비율이 높았으며, 단식성 나비의 비율이 높게 나타나고, 다화성 나비의 비율이 높게 나타났다. 배추흰나비 (Pieris rapae)는 600 m 이하의 고도에서 서식하고, 큰흰줄표범나비 (Argynnis ruslana), 먹그늘나비 (Lethe diana)는 900 m 이상의 고도에 서식하며, 특히 큰흰줄표범나비 (Argynnis ruslana)는 1,000 m 이상에서 서식하고 있었다. 본 연구를 바탕으로 지속적인 모니터링 실시를 통해 지리산에서 기후변화에 따른 나비의 고도 분포 변화 및 다양성 변화 양상을 확인할 수 있을 것으로 생각된다.

In animals, structural coloration is the production of color by microscopically structured surfaces of many birds as well as many butterfly wings and beetles wing cases. This structural coloration is caused by interference effects rather than by pigments. It has been known that the colors are produced when a material is scored with fine parallel lines, formed of one or more parallel thin layers, or otherwise composed of microstructures on the scale of the colour’s wavelength. Current research is performed using light and scanning electron microscopes to examine the fine structural characteristics of scales in the three species of iridescent butterflies Papilio maackii, Charaxes tiridates and Anaea glaucone. It has been revealed that the structural coloration of these butterflies is responsible for the blues and greens of the scales of wings. In addition, the reflected color depends on the viewing angle, which in turn controls the apparent spacing of the structures responsible for specific color patterns of the wing scales.

In the Northern Hemisphere, northward shifts due to global warming are apparent in various organisms such as butterflies, birds, and plants. In South Korea, ranges of butterflies are expected to shift northwards. We tested whether distribution limits of Korean butterflies shift northwards. We used two Korean butterfly atlases (1938-1950, 1977-2011) for analysis of the range shifts. Northern limits of southern species moved significantly northward (ca. 60 km) for 50 years, whereas southern limits of northern species did not significantly move northwards nor southwards. This finding parallels with other studies on butterflies and birds in Europe and North America.

Myanmar, which has a total area of 678,500 square kilometers (262,000 sq mi), is the largest country in mainland Southeast Asia, and the 40th-largest in the world. It lies between latitudes 9° and 29°N, and longitudes 92° and 102°E. Much of the country lies between the Tropic Of Cancer and the Equator. It lies in the monsoon region of Asia, with its coastal regions receiving over 5,000 mm (196.9 in) of rain annually. Northern regions of the country are the coolest, with average temperatures of 21 ℃ (70 ℉). Coastal and delta regions have an average temperature of 32 ℃ (86.9 ℉). This expedition was conducted two times in two years. First, collecting expeditions of insect were conducted in Popa resort, Myanmar from Aug. 7, 2011 to Aug. 17, 2011. Second, collecting expeditions of Insect were conducted in Alaungdaw Kathapa National Park (AK National Park), Myanmar from Feb. 2, 2012 to Feb. 9, 2012. As a Protected area of the Forest department, these areas were almost natural conservation field and limited to collection actions. Usually on day time, butterflies collected by sweeping net, like various plants, they shows high diversity. Some Papilionidae species are difficult to meet because they fly very high and fast, usually they visit to top of trees. Up to now, 60 species of 7 families were confirmed. Materials are expected more than 100 species belonging to 10 families but it was difficult to identification because of lack of references of this areas. Among them, with rare species, manifold butterflies are provided with photos, ecological notes and activities of Myanmar.

The phylogenetic relationships among true butterfly families (superfamily Papilionoidea) have been a matter of substantial controversy, and that debate has led to several competing hypotheses. Two of the most compelling of those hypotheses involve the relationships of (Nymphalidae + Lycaenidae) + (Pieridae + Papilionidae) and (((Nymphalidae + Lycaenidae) + Pieridae) + Papilionidae). In this study, approximately 3,500 nucleotide sequences from cytochrome oxidase subunit I (COI), 16S ribosomal RNA (16S rRNA), and elongation factor-1 alpha (EF-1α) were sequenced from 83 species belonging to four true butterfly families, along with those of eight outgroup species belonging to the skipper family (superfamily Hesperioidea). These sequences were subjected to phylogenetic reconstruction via Bayesian Inference (BI), Maximum Likelihood (ML), and Maximum Parsimony (MP) algorithms. All phylogenetic analyses among the four true butterfly families strongly indicated a sister relationship between the Nymphalidae and Lycaenidae on one hand, and relatively strongly indicated a sister relationship between the Pieridae and Papilionidae on another hand, thus supporting the hypothesis: (Nymphalidae + Lycaenidae) + (Pieridae + Papilionidae).

There has been a substantial controversy on the phylogenetic relationships among butterfly families and several competing phylogenetic hypothesis have been suggested. Among them the relationships of (((Nymphalidae + Lycaenidae) + Pieridae) + Papilionidae) has been further widely accepted. In this study, we sequenced EF1-α, COI, and 16S rRNA from 62 species belonging to four true butterfly families, Papilionoidea. Phylogenetic analyses using BI, ML, and MP showed that the traditionally recognizable families were strongly supported as monophyletic groups, with the exception of Nymphalidae, wherein the singly included species of Danainae was placed as basal lineage of the Nymphalidae + Lycaenidae group. Phylogenetic relationships among families supported the sister group relationship of Nymphalidae and Lycaenidae strongly by all analyses and placed Papilionidae as the most basal lineage of the Papilionoidea. On the other hand, the relationships of Nymphalidae and Lycaenidae group to Pieridae were either unresolved, revealing trichotomy, or the relationships of (((Nymphalidae + Lycaenidae) + Pieridae) + Papilionidae) as previously supported by several morphological and molecular works supported. Detailed within-family relationships among some genera also are shown in the presentation.

In order to find phenological change of butterflies due to global warming, we analyzed weekly monitoring data of butterfly at Gwangneung forest in 1958 and 2004. It was tested whether the timing of first flight and mean flight of butterflies in 2004 became earlier due to global warming compared with those in 1958 and whether the duration of flight period became longer. No significant difference was found in timing of first flight and in duration of flight period between 1958 and 2004. Furthermore, species showing delayed timing of mean flight was more abundant than species showing earlier timing of mean flight. Hence, the results do not confirm the predicted changes of phenology due to global warming. We discussed reasons on the non-apparent phenological changes despite the increase of temperature, and the problems and solutions in butterfly study on Korean butterfly fauna in utilization of butterflies as indicator for global warming.

곤충관의 연중 전시용으로서 붉은 색 계통의 화려한 나비로서 공급하기 위하여 네발나비류의 계대사육법 체계확립을 위해 일련의 시험을 수행하였다. 먼저 실내 제대사육용 인공사료를 개발하기 위해 3종의 사료를 공시한 결과 종에 따라 선호하는 사료의 종류가 달랐으나 Bu사료가 대체로 사육 성적이 양호하였으며 사료 중 기주잎 분말은 냉동 건조한 것이 좋았으며 C/N율은 1:1이 가장 양호한 결과로 나타났다. 또한 발육단계 별 냉장가능기간을 조사한 결과 알의 경우 에서는 3일간, 에서는 5일간 저장이 가능하였고 번데기의 경우에는 저온에 오래 보관할수록 기형 나비의 출현율이 높아 에서 최대 15일간 냉장 가능한 것으로 판단되었다. 나비의 장기 저온보호시험을 통해 냉장전의 흡밀기간, 냉장 온도에는 관계없이 법 장기간이 생존을, 산란전기간 및 산란수에 영향하였으며 60일까지 냉장이 가능한 것으로 나타났다. 네발나비는 기주식물의 자극없이는 산란하지 않아 페트리 접시를 이용한 간이 인공산란용 키트를 개발하여 기주식물(한삼덩굴)잎의 에테르 물추출물을 처리한 결과 암컷 1마리 당 평균 개를 산란하였다. 이러한 결과들을 종합하여 네발나비류의 연중 실내제대사육 체계도를 완성하였다.
