Silometopus elegans

Local name: knøttspydedderkopp

Unknown

Overview

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

Silometopus elegans faces significant pressure from habitat degradation in its specialized coastal and wetland environments. Agricultural intensification and urban development have reduced the availability of suitable damp grassland and marsh edge habitats where this spider constructs its distinctive webs. Climate change poses additional risks through altered precipitation patterns that could affect the moisture-dependent ecosystems this species requires for survival.

Threat summary

Habitat

This species inhabits damp grasslands, marsh edges, and coastal wetland areas where it builds small sheet webs close to the ground. It shows a strong preference for areas with consistent moisture levels and dense low vegetation that provides both hunting opportunities and protection from desiccation.
