Overview

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

Storøjet bugsvømmer faces severe habitat degradation from agricultural intensification and urban development around its freshwater breeding sites. Water pollution from agricultural runoff and eutrophication has significantly reduced water quality in the shallow, vegetated ponds and slow-moving streams this species requires. Climate change-induced alterations to precipitation patterns threaten the stability of these ephemeral wetland habitats, while invasive species competition further pressures remaining populations.

Threat summary

Habitat

This aquatic bug inhabits shallow, vegetated freshwater environments including ponds, slow-moving streams, and temporary wetlands with abundant emergent vegetation. It requires clean water with moderate nutrient levels and dense aquatic plant communities that provide both shelter and hunting grounds for small invertebrate prey.
