C-18 Changes in adult emergence timing of Luehdorfia puziloi (Erschoff) (Lepidoptera: Papilionidae) responding to temperature rise in South Korea Il-Kwon Kim1, Jong-Woo Nam2, 1Division of Forest Biodiversity, Korea National Arboretum, Pocheon, Republic of Korea 2Human Resource Training Team, Baekdudaegan National Arboretum, Bongwha, Republic of Korea [email protected] Keywords: Lepidoptera, Luehdorfia puziloi, 50% emergence rate, soil temperature increase Luehdorfia puziloi (Erschoff, 1872) is a monophagous butterfly species that occurs only once during spring in a year and distributed nationwide in Korea. These facts make the butterfly a perfect candidate to investigate insect responses to climate change, particularly temperature rise. From 2012 to 2014 the adult emergence was monitored to assess how the species responds to temperature rise in the country. Monitoring sites were located in four different provinces, two in the northern part of the country and the other two in the southern part. In each site a emergence cage was set up with 60 to 70 pupae and a HOBO data logger to record the soil temperature of the site from February to April. The earliest record from literatures and specimen collection data was 28th of March in Geojae-gun, a far south location of the country, during the late 90’s. In 2013, the butterfly started emerging in a southern site, Namhae-gun, from 20th of March, and it was the earliest record so far. The emergence patters during the three years clearly showed that the adult emergence reached to 50% emergence rate faster as the soil temperature rose each year. ※ The study was supported by Korea National Arboretum (Project No. KNA1-2-11). .
