This study was conducted for investigation of habitat and development of indoor-rearing conditions of peacock butterfly, Inachis io (Linnaeus). Three different region, Mt. Kwangduk-san, Mt. Hae-san and Mt. Taebaek-san in Kangwon-do, was selected for investigation of domestic distribution and ecological environment of peacock butterfly. In result, there are many butterflies in the only two region, Mt. Kwangduk-san and Mt. Hae-san. On 16th April, 4 overwintered butterflies were observed in Mt. Hae-san. At the end of June and early in July, 51 individual next generation’s butterflies were observed in Mt. Kwangduk-san and Mt. Hae-san. For development of indoor-rearing conditions, collected each 15 male and female peacock butterflies was reared in a room condition. Female butterflies laid eggs in the egg cluster on the underside of host-plant’s leaves, Urtica angustifolia Fisch., in the ovipositioning room. We took 11 egg cluster with average 404.6 ± 23.6 eggs. Hatchablity of eggs was 92.3%, and the eggs hatched within 5.1 ± 0.9 days from the day of oviposition under high temperature, long day condition(25oC, 14L:10D). The larval period was 18.3 ± 1.0 days under high temperature, long day condition(25oC, 14L:10D), showing 81.0% pupal ratio. The headwidth of each developmental larval stage were 0.37 ± 0.01mm(1st instar), 0.66 ± 0.02 mm(2nd instar), 1.07 ± 0.05 mm(3rd instar), 1.81 ± 0.07(4th instar), 2.76 ± 0.08(5th instar). The pupal period was 8.4 ± 0.6 days, and the emergence rate was 87.5%.
