Overview

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

Diaphorus oculatus faces significant pressure from habitat degradation in its restricted wetland environments, where agricultural expansion and urban development have reduced suitable breeding sites. Water pollution from agricultural runoff and industrial discharge poses additional risks to this aquatic-dependent species. Climate change-induced alterations to precipitation patterns threaten the seasonal water cycles essential for its reproductive success.

Threat summary

Habitat

This species inhabits freshwater wetlands, shallow ponds, and slow-moving streams with abundant aquatic vegetation. It requires clean, well-oxygenated water with stable seasonal flooding cycles for successful reproduction and larval development.
