It is introduced to Suwanosejima in the Tokara Group, Taramajima of the Miyako Group, and Kuroshima of the Yaeyama Group.

Habitat and Ecology


It is a common species through most of its range.

Population Trend


Major Threats

Globally there are no major threats to this species. It might be locally threatened by agrochemical pollution (land and water) and the conversion of habitat to intensively cultivated land.

Conservation Actions

It occurs in a number of protected areas.

Red List Status

Least Concern (LC)


Listed as Least Concern since, although its Extent of Occurrence is probably less than 20,000 km2, it is common and adaptable with a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
