Clubiona caerulescens

Unknown

Overview

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

The glanzende zakspin faces severe habitat degradation due to intensive agricultural practices and urban development across its limited European range. Pesticide applications in agricultural areas directly impact spider populations and reduce prey availability. Climate change poses additional stress through altered precipitation patterns affecting the moisture-dependent microhabitats this species requires for survival.

Threat summary

Habitat

This spider species inhabits moist grasslands, meadows, and woodland edges with dense vegetation cover. It requires stable microhabitats with adequate moisture levels and abundant invertebrate prey, typically found in semi-natural grassland ecosystems.
