Overview

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

Hebrus pusillus faces significant pressure from wetland habitat degradation and loss across its limited range. Agricultural intensification and urban development have reduced the availability of suitable shallow water margins and muddy substrates essential for this species. Water pollution from agricultural runoff and industrial sources further compromises the quality of remaining habitats, affecting both the bug's survival and its invertebrate prey base.
