Hydroporus discretus

Unknown

Overview

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

Hydroporus discretus faces severe threats from habitat degradation and water pollution in its limited aquatic environments. The species' extremely restricted range makes it particularly vulnerable to local environmental changes, with agricultural runoff and urban development posing significant risks to water quality in its specialized freshwater habitats. Climate change-induced alterations to precipitation patterns and temperature regimes further threaten the delicate aquatic ecosystems this diving beetle depends upon.
Threat summary

Habitat
