Trematocephalus cristatus

Local name: nålsögespindel

Unknown

Overview

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

The nålsögespindel faces significant pressure from habitat degradation in its specialized wetland environments. Agricultural intensification and drainage of marshlands have reduced suitable breeding sites, while climate change alters the hydrological patterns essential for this species' survival. Urban development and infrastructure projects continue to fragment remaining populations across its limited range.
