The Ministry of Environment in Korea published 'The Compilation of National List of Indigenous Insect Species of the Korean Peninsula' in 1996 including 11,853 species. The National Institute of Biological Resources (NIBR) originally compiled the national species list of insects to establish a national inventory of endemic biological assets with the joined efforts from all distinguished Korean taxonomists since 2008. For the convenience of scores of professional taxonomic groups participating in the project concurrently, the NIBR has developed the NIBR inventory description method and inventory system from 2008 to 2016. For nine years in this study, the NIBR has established the national insect inventory of 16,558 species including Collembola. The insect fauna of the Korean Peninsula comprises 565 families from 30 orders. The largest orders are Coleoptera (110 families, 4,318 species), Lepidoptera (67 families, 3,733 species), Hymenoptera (61 families, 3,151 species), Hemiptera (88 families, 2,013 species) and Diptera (79 families, 1,944 species). The fractions of the main insect orders in the fauna of the Korean peninsula correspond to those in the Holarctic temperate zone. And totally 13 volumes of national list of insect species in Korea were published.
