Cnephaeus japonensis

Declining

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Cnephaeus japonensis faces significant pressure from urban development and agricultural expansion across its limited range in Japan. The species' specialized habitat requirements make it particularly vulnerable to forest fragmentation and the conversion of native woodlands to monoculture plantations. Climate change poses an additional threat by altering the moisture and temperature conditions essential for this beetle's survival and reproduction.

Threat summary

Habitat

This beetle species inhabits deciduous and mixed forests in Japan, particularly favoring areas with rich leaf litter and decaying organic matter. It requires specific microhabitat conditions including adequate moisture levels and stable temperature ranges found in mature forest ecosystems.
