Metcalfa pruinosa (Hemiptera: Flatidae) is a invasive and harmful insect in South Korea. It is originated from the Nearctic region. Since M. pruinosa was first identified in South Korea in 2005, it dispersed throughout the country. In this study, we investigated the dispersal ability of M. pruinosa in the field in three different levels: 1) short distance movement, 2) flying movement, and 3) dispersal distance in large area in the two different landscape types (open canopy and forest with covered canopy). Our results showed that the movement ability of M. pruinosa was weak in walking. However, it displayed long dispersal distance that increasing dispersal distance in each year. These results can be used for modelling dispersal distance of the species.
