Winter flight of flies (Diptera) in Hongneung Arboretum, Seoul, Korea

Winter phenology (diapause and activity) of insects is expected to change more significantly than that of other seasons, because temperature will increase more in winter than in other seasons in temperate regions. However, studies on winter phenology of insects are rare. It is expected that winter flights of flies (Diptera) will increase as climate warms. This study aims to find the relationship between flight of flies and temperature. The survey on flies and weather (temperature and rainfall) was carried out in the Hongneung Arboretum in Seoul, Korea. Flies were collected weekly from December 2012 to February 2013 using sweeping and Malaise trap. In the survey, 106 flies belonging to 28 morphospecies and 17 families were collected. Richness and abundance of flies were positively correlated with temperature.
