Protecting endangered species Miyamashijimi(butterflies)

NAGANO WORKS and Nagano Prefecture have signed the agreement on biodiversity partnerships to protect Miyamashijimi butterflies, an endangered species. The butterflies are classified in the family Lycaenidae of the order Lepidoptera and their adults are small, about 2-3 centimeters in length and are designated as Class IB endangered species in the Red List of the Ministry of the Environment. The reason for the decrease in the number of butterflies was a decrease in the number of Komatsunagi (false indigo) which are both feeding and spawning sites of the butterflies. Nagano Works succeeded in testing Miyamashijimi egg production by planting Komatsunagi inside the plant. In the future, we will continue to promote the growth of Komatsunagi, the reproduction of Miyamashijimi and the conservation of the environment.
