Abstract
An investigation on the habitation of Callipogonrelictus Semenov, 1899 in Gwangneung forest was carried out, where the Korea National Arboretum is located. In an investigation spanning the last eleven years (2007-2017), 22 emergence holes, nine pupal chambers, six adults, and two larvae of C.relictus were identified. In this study, biological information about habitation of C.relictus is provided by comparing and combining the results of this investigation with a survey conducted in Ussurisky Nature Reserve, Russia, in 2015. The distribution is also reviewed to include the Korean Peninsula and a new location of South Korea is added to the distribution for C.relictus.
