It is difficult to see black-veined whites in South Korea for several reasons. First, the southern limit of this species range, which is the central region of South Korea, is going upward due to global warming. For this reason, black-veined whites are rarely found in South Korea while they are easily seen in North Korea and Yanbian. Second, they were indiscriminately captured and their habitats were destroyed by insect collectors, particularly during the Japanese colonial era. The Korean government is making efforts to protect black-veined whites from extinction - this species is currently designated as Endangered Wild Species Class I of Korea by the Ministry of Environment.
