Overview

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

The parallell dvärgdykare faces severe population decline due to habitat degradation from agricultural runoff and urban development around its specialized aquatic breeding sites. Water pollution from pesticides and fertilizers has significantly reduced the quality of shallow wetland areas essential for larval development. Climate-induced changes in precipitation patterns are altering water levels in critical breeding pools, disrupting the species' reproductive cycle.

Threat summary

Habitat

This aquatic beetle inhabits shallow, vegetated wetlands, temporary pools, and slow-moving streams with abundant emergent vegetation. It requires clean, well-oxygenated water with stable seasonal flooding patterns for successful reproduction and larval development.
