Hydrotarsus pilosus

Unknown

Overview

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

Hydrotarsus pilosus faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range. Water pollution from agricultural runoff and industrial discharge poses an additional significant threat to this aquatic beetle species. Climate change-induced alterations to precipitation patterns and water temperature regimes further compromise the specialized freshwater habitats this species requires for survival.

Threat summary

Habitat

This aquatic beetle inhabits shallow freshwater environments including slow-moving streams, ponds, and wetland margins with dense aquatic vegetation. The species requires clean, well-oxygenated water with specific temperature ranges and abundant organic matter for both larval development and adult feeding.
