Overview

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

The zomerpanterspin faces severe habitat degradation due to intensive agricultural practices and urban development across its limited European range. Coastal dune systems and sandy heathlands where this wolf spider specializes are increasingly fragmented by tourism infrastructure and recreational activities. Climate change poses additional pressure through altered precipitation patterns that affect the species' preferred dry, sandy microhabitats and prey availability.

Threat summary

Habitat

This wolf spider inhabits coastal sand dunes, sandy heathlands, and dry grasslands with sparse vegetation across northwestern Europe. It requires well-drained sandy soils with open patches for hunting and burrow construction, typically in areas with minimal human disturbance.
