This species is widespread but has a fragmented distribution. There is relatively little information available on population trends and threats. In Japan this species is listed as Vulnerable and in Russia it is listed as a rare species. The Chinese population could be a distinct species, but more research is required to clarify this. Listed as Data Deficient because of taxonomic uncertainty and lack of data.
