Abstract
Taraka hamada is known as the sole aphidophagous lycaenid butterfly in Korea. The species specifically preys upon Ceratovacuna japonica which lives in bamboo forests. During several years, the species has been received attention from the field of industrial insects in order to commercialize as a pet. However, an ecological character of the species have been unclear in Korea. We carried out a survey for basic ecology and distribution of the two species for 2010 to 2012. As the results, both species only cohabit at Pseudosasa japonica in our investigation. C. japonica is widely distributed from the host plant. Population density of T. hamada is synchronized with the density changes of C. japonica. Their densities are gradually decreased from the point to the investigation and significantly declined in mid-june. The maximum population density of both species shows at the basal part of a leaf. The last-larval instar of T. hamada may seem to be reaching at $4^{th}$ stage. The adults of T. hamada are killed within two minutes when they were exposed to the sun.
2010년부터 2012년까지 전국 각지 야외에서 조사한 바둑돌부전나비의 생태학적 특성은 다음과 같다. 1. 이대에 서식하는 일본납작진딧물은 바둑돌부전나비 유충의 먹이로서 지표로부터 폭넓게 분포하였으며, 조사 8회 차인 6월 13일부터 밀도가 현저히 감소하였다. 2. 일본납작진딧물과 바둑돌부전나비가 가장 많은 밀도를 보이는 곳은 줄기와 가장 인접한 부위이었다. 3. 바둑돌부전나비의 유충 예상 령수는 4령으로 추측된다. 4. 바둑돌부전나비 성충의 야외 노출 시 생존시간 조사 결과, 2분 이내에 사망하는 것으로 조사 되었다.
