Kumo Orange-tip and Small Luehdorfia Butterfly Habitat

The orange tip is a small white butterfly found in the mountains of central Honshu, including some lower mountain sites. Males have orange forewing tips, but females do not. Its caterpillars feed on mustard-family plants. A habitat is designated a prefectural Natural Monument in Niigata, while Toyama and Nagano protect the butterfly itself without restricting designation to particular sites.
