Granite‐derived soils are widespread in the farmland of K orea in general. In contrast, J eju I sland has mainly volcanic ash soils. Soils and weather condition in J eju I sland created a unique agricultural system. We identified the features of ground‐dwelling insects in farmlands of J eju I sland. This study was conducted in four areas ( S amdal‐ri and S usan‐ri in S eogwipo city, and D ongmyeong‐ri and S uwon‐ri in J eju city) in J eju I sland, K orea. Field surveys were carried out twice in summer ( J une) and autumn ( S eptember) in 2013. Ground‐dwelling insects were sampled quantitatively by using pitfall traps. As a result, in total 3322 individuals, 137 species, 48 families and 8 orders were investigated in farmlands of J eju I sland. Especially, members of C oleoptera and H ymenoptera accounted for a large proportion of ground‐dwelling insect communities. The numbers of species and individuals for major taxonomic groups showed significant regional and seasonal differences. This study implied that the seasonal and regional differences of ground‐dwelling insect communities were affected by surrounding land use patterns, life history patterns of each taxonomic group and farmland management.
