Overview

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

The grote nachtwolfspin faces severe habitat degradation from intensive agricultural practices and urban development across its limited range in the Netherlands and Belgium. Drainage of wetlands and conversion of natural grasslands to monoculture farming has fragmented remaining populations. Climate change compounds these pressures by altering the moisture regimes essential for this ground-dwelling spider's hunting and reproductive success.

Threat summary

Habitat

This large wolf spider inhabits moist grasslands, heathlands, and the edges of wetlands, particularly favoring areas with sparse vegetation and sandy or peaty soils. It requires specific moisture conditions and open ground for its ground-dwelling lifestyle and burrow construction.
