It inhabits rice paddies and ponds.
It is greatly reduced in numbers, and has recently been recorded from only four locations.
Habitat destruction and degradation are the major threats to this species, in particular due to changes in agricultural land use from rice to other crops, which is greatly reducing the habitat available to the species. Infrastructure development and water pollution pose additional threats.
The range of this species overlaps with a few protected areas. It is currently included in legislation by the Ministry of the Environment of the Republic of Korea.
