Porhydrus lineatus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Porhydrus lineatus faces severe threats from habitat degradation and water pollution in its limited freshwater environments. Agricultural runoff and urban development have contaminated the clean, well-oxygenated waters this diving beetle requires for survival. The species' extremely restricted range makes it particularly vulnerable to localized environmental changes, with even small-scale disturbances potentially causing population collapse.
Habitat
This aquatic beetle inhabits clean, well-oxygenated freshwater streams and small rivers with rocky or gravelly substrates. It requires pristine water conditions and is typically found in areas with moderate current flow and abundant aquatic vegetation.
