This is perhaps due to that relatively harsh environment, the wind-swept rocky grassland on the western side of the island, generally poor in organic litter.

. It was included into the Red Data Book of threatened wildlife of Okinawa and, though categorized as ’data deficient’ (DD), its habitat was proposed for preservation. According to our observations, the species is not confined to any characteristic or undisturbed biotope on Yonaguni-jima Island so perhaps habitat conservation is not the best approach, but considering that the total area of the island itself is only 28.8 square kilometers, the populations of the new and unique species are indeed worthy of legal protection.
