Limnichus pygmaeus

Unknown

Overview

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

Limnichus pygmaeus faces significant pressure from wetland habitat degradation and loss across its limited range. Agricultural intensification and urban development have reduced the quality of shallow freshwater habitats this beetle depends on for reproduction and survival. Water pollution from agricultural runoff and industrial sources further compromises the aquatic ecosystems where both larvae and adults feed on organic matter.

Threat summary

Habitat
