Hydroporus longulus

Unknown

Overview

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

Hydroporus longulus faces severe threats from habitat degradation and water pollution affecting its specialized aquatic environments. The species' extremely limited distribution makes it particularly vulnerable to localized environmental changes, with agricultural runoff and urban development posing significant risks to water quality in its remaining habitats. Climate change-induced alterations to precipitation patterns and temperature regimes further threaten the delicate ecological balance of the small water bodies this beetle depends upon.

Threat summary

Habitat

This aquatic beetle inhabits small, shallow freshwater pools, temporary ponds, and slow-moving streams with abundant vegetation and organic debris. It requires clean, well-oxygenated water with specific temperature and chemical conditions typical of pristine wetland ecosystems.
